    Default Calculating Total Head Loss

    I would like to add in a solar heater, however doing this I will need to add 140' (total) off 1.5" pvc pipe plus 8' vertical rise.

    I need to maintain a flowrate of 25 gpm since my SWG requires this pressure.
    I have a 3/4 hp Hayward superpump, specs say that with 50 ft of head I can maintain a flow rate of 31 gpm.

    I am trying to calculate the "head loss" of my total system, so far I have come up with:

    Hayward Sandfilter = 15 ft
    140' 1.5' pvc = 6 ft
    Solar panels = ? ft
    8' rise 1.5" pvc = ? ft
    10 elbows = 2ft
    Scimmer & drain = 0.2ft

    So it seems I am still way under 50 ft of head loss.
    Does anyone know the headloss for the 8ft rise?

    Anyone see any problem with my calculations?
