How Do You Calculate the Power Required for a Water Compressor?

[bluemoon2188]

Hi all,

I am involve in a group assignment where a water compressor will be used to produce high pressured water.

I would like to know if there a formula to calculate the amount of power needed to operate the water compressor.

Thanks

Welcome to PF.

I've never heard of a "water compressor". Water is largely incompressible. Do you mean water pump? Multiplying pressure and flow rate gives you power - and figure 75% efficiency (and make sure your units are right!).

Hi russ-watters

Thanks for the reply.

What you have said makes sense. A pump should provide an increase in water pressure.

Thanks for the reminder.

Water's still not compressible, but could it also perhaps be a pressure washer?
