    Pump Head

    What I need is conversions for pump head to PSI and I think you need conversion charts depending on system temp and fluid, glycol etc.

    The conversion of feet of head to psi IS dependent on the specific gravity of the fluid. The lower the SG, the higher the column of water required to produce 1 psi. This can be critical when using pump head to go to the curve and determine flow. The ASHRAE Applications Handbook has a chart in the chapter on Testing, Adjusting and Balancing.
