    Chiller diff pressure
    Our chilled water system is rated 4050 GPM 100psi with 40-45 diff pressure, is this differential the process demand? How can we use this to calculate primary chiller pump dynamic head and is this also affecting the secondary chiller pump TDH?:confused:

    where do the 45 psi come from,is it estimate or actual cal? Total psi= head(height)+ friction(horizontal)+(equipment); plus at least 10 psi. what is the second pump for ,heat plate?. so you have at least 1500 tons?
