Q3. What was centrifugal pump and difference between pump and compressor?
Ans. 
A centrifugal pump is a mechanical device used to transport fluids by converting rotational kinetic energy to hydrodynamic energy.
• Centrifugal pumps are commonly used in industries such as oil and gas, chemical, and water treatment.

• They work by using an impeller to create a low-pressure area at the center of the pump, which draws in fluid and then expels it at high pressure through the outlet.

• Pumps are used to transport...read more

Q4. What was NPSH? Types of pumps..
Ans. 
NPSH stands for Net Positive Suction Head. It is a measure of the pressure available at the suction side of a pump to prevent cavitation.
• NPSH is important in pump selection and operation.

• It is the difference between the total suction head and the vapor pressure of the pumped fluid.

• Insufficient NPSH can lead to cavitation, which can damage the pump and reduce its efficiency.

• Different types of pumps have different NPSH r...read more

Q1. 1. How you will select a heat exchanger for different type of fluids.
Ans. 
The selection of a heat exchanger for different fluids depends on factors such as fluid properties, flow rates, and heat transfer requirements.
• Identify the properties of the fluids such as viscosity, density, and thermal conductivity.

• Determine the flow rates and pressure drops of the fluids.

• Select the appropriate type of heat exchanger such as shell and tube, plate and frame, or spiral.

• Consider the heat transfer requir...read more

Q2. What Is reflux ratio.
Ans. 
Reflux ratio is the ratio of the amount of liquid refluxed to the amount of liquid that is being distilled.
• It is an important parameter in distillation processes.

• It helps in determining the efficiency of the distillation column.

• A high reflux ratio results in a higher purity of the distillate.

• Reflux ratio can be adjusted to optimize the distillation process.

• It is calculated as the ratio of the reflux flow rate to the di

Q1. Modes of Heat transfer
Ans. 
Modes of heat transfer include conduction, convection, and radiation.
• Conduction is the transfer of heat through a material without any movement of the material itself.

• Convection is the transfer of heat through the movement of fluids, such as air or water.

• Radiation is the transfer of heat through electromagnetic waves, such as the heat from the sun.

• Examples of conduction include touching a hot stove or holding a cold dr...read more

Q2. Design of distillation coloumn
Ans. 
Design of distillation column involves determining the number of trays, column diameter, and feed location.
• The number of trays is determined by the separation required and the reflux ratio.

• Column diameter is determined by the vapor and liquid flow rates.

• Feed location is determined by the composition of the feed and the desired product purity.

• Other factors to consider include pressure drop, heat transfer, and material s...read more
