Q1. Whats is NPSH and how its relevant for Cavitation?
Ans. 
NPSH stands for Net Positive Suction Head. It is a measure of the pressure available at the suction port of a pump to prevent cavitation.
• NPSH is important for preventing cavitation in pumps by ensuring that the pressure at the suction port is sufficient to avoid the formation of vapor bubbles.

• It is calculated by subtracting the vapor pressure of the fluid from the total suction head of the pump.

• If the NPSH available is...read more

Q2. How identify the seal failure? And what the procedure for seal failure?
Ans. 
Seal failure can be identified through visual inspection, pressure testing, and monitoring of leakage. The procedure for seal failure involves replacing the faulty seal and ensuring proper installation.
• Visual inspection for signs of wear, damage, or misalignment

• Pressure testing to check for leaks under pressure

• Monitoring of leakage to detect any increase in fluid loss

• Replace the faulty seal with a new one

• Ensure proper ...read more

Q3. How co- related Flow and Power in centrifugal Pump?
Ans. 
Flow and power in a centrifugal pump are related through the pump's performance curve.
• Flow rate and power consumption are directly related in a centrifugal pump.

• As flow rate increases, the power required to maintain that flow rate also increases.

• The pump's performance curve shows the relationship between flow rate and power consumption.

• Efficiency of the pump also plays a role in the relationship between flow and power.

Q4. How the coating repaire?
Ans. 
Coatings can be repaired by identifying the damaged area, preparing the surface, applying the new coating, and curing it properly.
• Identify the damaged area by inspecting the coating for cracks, peeling, or discoloration.

• Prepare the surface by cleaning it thoroughly and removing any old coating or debris.

• Apply the new coating using the appropriate method such as spraying, brushing, or dipping.

• Cure the coating properly b...read more
