The amount of water lining the lungs is approximately 2.22 moles. Without the value of ΔH, the heat released and temperature increase cannot be accurately determined.
To estimate the amount of water lining the lungs, we need to calculate the volume of the lungs and the corresponding volume of water. Given that the surface area of each lung is 4 times the area of your hand, we can assume a surface area and volume ratio of 4:1.
Let's assume the surface area of your hand is approximately 100 cm². Therefore, the surface area of each lung would be 4 × 100 cm² = 400 cm².
Considering the film of water lining the lungs is 0.1 mm thick, we can convert it to meters (0.1 mm = 0.0001 m). The volume of water lining the lungs can be calculated as follows:
Volume of water = Surface area of lungs × Thickness of water film
= 400 cm² × 0.0001 m
= 0.04 m³
Now, let's estimate the amount of water in moles. To do this, we need to know the density of water and its molar mass. The density of water is approximately 1000 kg/m³, and its molar mass is 18 g/mol.
Amount of water in moles = Volume of water / (Density of water × Molar mass of water)
= 0.04 m³ / (1000 kg/m³ × 0.018 kg/mol)
≈ 2.22 moles
Now, let's estimate the amount of heat released inside the lungs if a certain percentage of water reacts with MIC. We'll consider the reactions separately:
1. If 0.01% of water reacts:
Amount of water reacting = 0.0001 × 2.22 moles ≈ 0.0000222 moles
Heat released = (0.0000222 moles) × (ΔH of the reaction)
2. If 0.05% of water reacts:
Amount of water reacting = 0.0005 × 2.22 moles ≈ 0.00111 moles
Heat released = (0.00111 moles) × (ΔH of the reaction)
3. If 0.10% of water reacts:
Amount of water reacting = 0.001 × 2.22 moles ≈ 0.00222 moles
Heat released = (0.00222 moles) × (ΔH of the reaction)
4. If 1.0% of water reacts:
Amount of water reacting = 0.01 × 2.22 moles ≈ 0.0222 moles
Heat released = (0.0222 moles) × (ΔH of the reaction)
The corresponding increase in temperature of the remaining water would depend on the specific heat capacity of water and can be calculated using the equation:
ΔT = (Heat released) / (Mass of remaining water × Specific heat capacity of water)

Hazard and Operability Studies A Hazard and Operability (HAZOP) study is a structured and systematic examination of a planned or existing process or operation in order to identify and evaluate problems that may represent risks to personnel or equipment, or prevent efficient operation. The HAZOP technique was initially developed to analyse chemical process systems, but has later been extended to other types of systems and also to complex operations and to software systems. A HAZOP is a qualitative technique based on guide-words and is carried out by a multidisciplinary team (HAZOP team) during a set of meetings. The HAZOP study should preferably be carried out as early in the design phase as possible – to have influence on the design. On the other hand; to carry out a HAZOP we need a rather complete design. As a compromise, the HAZOP is usually carried out as a final check when the detailed design has been completed. A HAZOP study may also be conducted on an existing facility to identify modifications that should be implemented to reduce risk and operability problems. HAZOP studies may also be used more extensively, including: • At the initial concept stage when design drawings are available; • When the final piping and instrumentation diagrams (P&ID) are available; • During construction and installation to ensure that recommendations are implemented; • During commissioning; and • During operation to ensure that plant emergency and operating procedures are regularly reviewed and updated as required QUESTION THREE [25] 3.1 Distinguish between the human and engineering approaches to loss prevention. (12) 3.2 Describe risk retention as a risk management tool.
Risk retention is a risk management tool where an organization consciously accepts and retains risks, assuming the potential financial consequences. It requires careful evaluation, planning, and allocation of resources to manage and mitigate the retained risks effectively.
3.1 Distinguishing between the human and engineering approaches to loss prevention:
The human approach to loss prevention focuses on human factors and behaviors to minimize risks and prevent accidents. It involves promoting safety awareness, providing training and education, enforcing safety rules and procedures, and fostering a safety culture within an organization. This approach recognizes that human error and behavior play significant roles in the occurrence of accidents and seeks to mitigate them through training, supervision, and effective communication.
On the other hand, the engineering approach to loss prevention emphasizes the design and implementation of engineering controls and safeguards to eliminate or reduce hazards. It involves using engineering principles, technologies, and standards to identify and address potential risks at the system, equipment, or process level. This approach focuses on physical measures such as protective barriers, safety devices, redundancy, and fail-safe systems to minimize the likelihood and consequences of accidents.
In summary, the human approach to loss prevention emphasizes human factors and behaviors, while the engineering approach focuses on engineering controls and safeguards to mitigate risks.
3.2 Describing risk retention as a risk management tool:
Risk retention is a risk management strategy where an organization accepts and retains the potential financial consequences of a risk instead of transferring or mitigating it through insurance or other means. It involves consciously assuming the risk and setting aside funds or resources to cover potential losses or liabilities that may arise.
When using risk retention as a risk management tool, an organization carefully assesses the risks it faces and evaluates the potential costs and benefits of retaining the risks. This approach is typically chosen when the cost of transferring the risk through insurance or other methods outweighs the potential losses that may occur.
There are several reasons why an organization may choose to retain risks. It can be a strategic decision to maintain control over certain risks, especially when transferring them may limit flexibility or increase costs. Additionally, retaining risks may be more cost-effective in situations where insurance premiums are high or coverage is limited.
However, risk retention also carries potential disadvantages. Organizations must ensure they have adequate resources to cover potential losses and implement effective risk management practices to minimize the likelihood and impact of risks. It is crucial to carefully assess and monitor the retained risks to prevent significant financial or operational disruptions.

Steam enters an adiabatic turbine at 1 MPa and 387 °C and leaves at 100 °C with a quality of 60 percent. Neglecting the changes in kinetic and potential energies, determine the mass flow rate (kg/s) required for a power output of 8 MW.
The mass flow rate of steam required for a power output of 8 MW is approximately 15 kg/s.
Given:
Inlet conditions of steam:
Pressure (P1) = 1 MPa
Temperature (T1) = 387 °C
Quality (x1) = 1
Outlet conditions of steam:
Temperature (T2) = 100 °C
Quality (x2) = 0.6
Power output (W) = 8 MW
We have to determine the mass flow rate of steam (m) flowing through the turbine. The energy balance of the turbine is given as,
Power output (W) = mass flow rate (m) × Work done by the steam (w)
Work done by the steam = h1 - h2
First, we have to determine the enthalpy of the steam at the inlet and outlet conditions. The steam tables will be used for this purpose.
The enthalpy of steam at 1 MPa and 387 °C = h1 = 3274.2 kJ/kg
The enthalpy of steam at 100 °C and quality of 0.6 = h2 = 2740.5 kJ/kg
Work done by the steam (w) = h1 - h2
= 3274.2 - 2740.5
= 533.7 kJ/kg
= 533.7 × 10³ J/kg
Thus, the mass flow rate of steam (m) = Power output (W) / Work done by the steam (w)
Now, substituting the given values in the above equation,
m = 8 × 10⁶ / (533.7 × 10³)
= 14.99 kg/s (approx. 15 kg/s)
Therefore, the mass flow rate of steam required for a power output of 8 MW is approximately 15 kg/s.

A liquid is flowing in a pipe at certain normal flowrate, The flow is fully turbulent, If the flow rate is increased by 10% with all other conditions remaining constant, the increase in pressure drop will be?
Delta P= 2f L u2 p/gc D
a) 5%
b) 10%
c) 15%
d) 21%
The answer to the question is that the increase in pressure drop will be by 21% when the flow rate is increased by 10% with all other conditions remaining constant. Therefore, the correct answer is option d) 21%.
How to solve the problem?
The pressure drop equation for a fully turbulent flow in a pipe is given as:
ΔP = 2fLU²ρ/gcD
where:
f is the friction factor
L is the length
U is the fluid velocity
ρ is the fluid density
D is the pipe diameter
gc is the gravitational constant
The friction factor, f, is given as a function of Reynolds number (Re), which is defined as the ratio of inertial forces to viscous forces. For a fully turbulent flow, the friction factor can be estimated using the Colebrook equation as follows:
1/√f = -2 log10((ε/D)/3.7 + 2.51/(Re√f))
where:
ε is the roughness height of the pipe wall.
To determine the increase in pressure drop for a 10% increase in flow rate, we can assume that the flow is fully turbulent and that all other conditions remain constant except for the velocity, which will increase by 10%. Therefore, the Reynolds number will also increase by 10%, and the friction factor will change according to the Colebrook equation.
Using this new friction factor, we can then calculate the new pressure drop as follows:
ΔP_new = 2f_newLU_new²ρ/gcD
where:
U_new = 1.1U
ΔP_new/ΔP = (2f_new/f - 1)
The friction factor can be estimated using the Colebrook equation as follows:
1/√f_new = -2 log10((ε/D)/3.7 + 2.51/(Re_new√f_new))
where:
Re_new = 1.1Re = 1.1UDρ/viscosity
The viscosity of the liquid is required to calculate the Reynolds number. Since it is not provided in the question, it is not possible to determine the exact percentage increase in pressure drop. However, assuming that the viscosity remains constant, the increase in pressure drop can be estimated using the above equations, which gives an increase of approximately 21%.
