How can I test how high a water pump can pump to, using only pressure simulation?

A pump is said to be capable of pumping water up to 100 meters, but I don't want to confirm that by actually putting up a very long pipe to that height. I know that pressure is related to height, so putting pressure at the output end of the pump would simulate different heights. Any suggestions how I can rig a contraption to do this? Thanks.How can I test how high a water pump can pump to, using only pressure simulation?*you can go by the 1st answer as pressure gauge near the pump discharge would give a maximum pressure inclusive of losses.

As the losses are more[due to piping congetion or rasistance from the equipment to which it is pumping.] then the discharge head will be decreased.



*Simply, in case of a centrifugal pump,close the discharge valve fully for a moment and check the discharge pressure.

This is the maximum pressure ,your pump will pump.

*Dont do this if the pump is positive displacement pump/regenerative turbine pump.



Edit: Discharge head means pumping height in your case.How can I test how high a water pump can pump to, using only pressure simulation?Install a pressure gauge at the pumps diischarge line and note that p=wh. H =p/w, H =p{(144)/62.4}/3.28 meters

Pressure expected therefore in psi, is p={62.4/144}3.28

p=14.9 psi

A pressure gauge of 0 to 50 psig range would be sufficient to indicate the expected pressure.
