Calculating Chiller Nominal Flow and Pressure to Process 
•  Flow rate: Obtain the flow reading from the appropriate pump curve. 
•  Pressure: Obtain a corresponding pressure reading from the pump curve you selected, 
then subtract the one-pump pressure drop listed in the above table using the 
appropriate chiller hp and flow rate.
