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. What is Heat of formation
Ans. 
Heat of formation is the energy released or absorbed when one mole of a compound is formed from its elements in their standard states.
• Heat of formation is also known as standard enthalpy of formation.

• It is typically measured in units of kJ/mol.

• Negative heat of formation indicates exothermic reaction, while positive heat of formation indicates endothermic reaction.

• For example, the heat of formation of water (H2O) is -28

Q1. What does grade in cement means
Ans. 
Grade in cement refers to the strength of the cement mixture.
• Grade in cement is a measure of the compressive strength of the cement mixture.

• It is usually denoted by a number, such as 32.5 or 42.5, which indicates the strength in megapascals (MPa).

• Higher grade cement is used for construction of structures that require higher strength, such as bridges and high-rise buildings.

• The grade of cement is determined by testing t...read more
