General Notes:

Note: Refer to the "Terms and Conditions" in the 'About' section before using the software.

1) Pump Power Calculations is a software program that can be used to estimate the power requirement of a pump.

2) You may use 'Piping Pressure Drop Calculator', available in this site to find the pressure drop in the piping.

3) The procedure is based on GPSA Engineering Data Book - 14th Edition.

4) 'Submit' button to be clcked when any changes are made to the input so the program updates the calculation.

5) If you notice any error, please let us know, so that can be rectified.
