Q5. What are the modes of heat transfer?

Ans : The modes of heat transfer are conduction, convection, and radiation.

Q6. What are different types of IC engines?

Ans : There are two main types of IC engines: spark ignition (SI) engines and compression ignition (CI) engines. Spark ignition (SI) engines use a spark plug to ignite the fuel-air mixture, commonly used in gasoline engines. Compression ignition (CI) engines rely on the heat generated by compressing the air-fuel mixture to ignite it, commonly used in diesel engines. Other types include rotary engines, two-stroke engines, and four-stroke engines.

Q7. What is heat exchanger and it’s working?

Ans :

• A heat exchanger is a device used to transfer heat between two or more fluids.
• Heat exchangers are used in various industries such as chemical, power, and HVAC.
• They work by allowing two fluids to flow through separate channels, with heat transferring from one fluid to the other.
• Common types of heat exchangers include shell and tube, plate and frame, and finned tube.
• Heat exchangers can be used for heating, cooling, or both.
• Efficiency of a heat exchanger is determined by factors such as flow rate, temperature difference, and surface area.
• Regular maintenance is important to prevent fouling and corrosion, which can reduce efficiency and lifespan.

Q8. What are various types of flow meters?

Ans : Flow meters are devices used to measure the flow rate or quantity of a gas or liquid moving through a pipe.

• Differential pressure flow meters
• Positive displacement flow meters
• Velocity flow meters
• Mass flow meters
• Open channel flow meters

Q9. Working of flow meters?

Ans : Flow meters measure the rate of fluid flow in a pipe or channel.

• Flow meters work by measuring the velocity of the fluid and the cross-sectional area of the pipe or channel.
• There are different types of flow meters such as differential pressure flow meters, positive displacement flow meters, and electromagnetic flow meters.
• Flow meters are used in various industries such as oil and gas, water treatment, and food and beverage.
• Examples of flow meters include turbine flow meters, ultrasonic flow meters, and vortex flow meters
