Re: Non pressurized solar water heater with boosting pump
Is pump above or bellow the tank? If it is above than that might cause the problem. NPSH of the pump - Net Pressure Suction Head is pump parameter that tells how big head in front of the pump should be in order to pump work without cavitation. You should calculate head in front of the pump and compa...

Re: Flowrate in a suction line
When you say negative - do you mean pressure under atmospheric value?
Calculators are working with absolute pressure value so you should be able to calculate it.

Re: How to prove relieving capacity of a PSV Discharge Line
q - is maximum flow capacity for known head loss (pressure drop), internal pipe diameter and resistance coefficient of pipe line system. So, enter head loss in - m, internal pipe diameter in mm and resistance coefficient K, and calculate maximum flow. If it is more than you have to check than relief...
