Help me calculate it
Thread Content
Our facility has a pump whose inlet pressure ranges from 2.0 to 2.4 megapascals, and the water temperature is between 130 and 150 degrees Celsius. Sometimes, due to the load on the system, the water temperature can be much higher than this range. I would like to know at what temperature above this level cavitation will occur; the required net positive suction head for this pump is 6.1 meters
Cavitation occurs when the vaporization temperature of water is reached by subtracting the net positive suction head under pressure.
I don’t understand; could you help calculate it?

Cavitation occurs when the inlet pressure is lower than the saturated vapor pressure of the liquid at that temperature.
