Calculating thrust on a PWC

What equation(s) can I use to calculate thrust at various RPM for various PWC impellers? I realize that it will depend on the intake channel size, and venturi nozzle diameter, so I will use the same sizes for all calcs.

I would like to create a table similiar to the following:

Concord 15/20
RPM Thrust, lbs
7000 ?
7100 ?
7200
7300
7400
7500
7600
7700

Concord 16/21
RPM Thrust, lbs
7000 ?
7100 ?
7200
7300
7400
7500
7600
7700

etc.

The impellers in question spin in a 155mm pump.

Can you guys help me out?

Thanks
