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.
