Q2. Npsh of pump condenser
Ans. 
NPSH of a pump condenser refers to the Net Positive Suction Head required for the pump to operate efficiently.
• NPSH is a critical parameter in pump selection and operation

• It is the difference between the absolute pressure at the pump suction and the vapor pressure of the liquid being pumped

• If NPSH available is less than NPSH required, cavitation may occur

• Factors affecting NPSH include pump design, fluid properties, and

Q1. Why syphon type pg use in steam line
Ans. 
Syphon type pressure gauges are used in steam lines to protect the gauge from high temperatures and prevent damage.
• Syphon type pressure gauges protect the gauge from high temperatures in steam lines

• They prevent direct contact of the gauge with steam, which can cause damage

• Syphons also help to cool down the steam before it reaches the gauge, ensuring accurate readings

Q1. Types of steam trap and it's uses
Ans. 
Steam traps are devices used to discharge condensate and non-condensable gases from steam systems while preventing steam from escaping.
• There are different types of steam traps such as mechanical, thermostatic, and thermodynamic traps.

• Mechanical traps operate based on the difference in density between condensate and steam.

• Thermostatic traps use temperature-sensitive elements to open and close the trap.

• Thermodynamic trap...read more
