Homework Help: Engineering hydraulics question

  1. Sep 28, 2012 #1
    1. The problem statement, all variables and given/known data

    Points A and B are separated by 3000 ft of new 6-in schedule-40 steel pipe. 800 gpm of 60 deg F of water flow from point A to point B. Point B is 60 ft above point A. What must be the pressure at Point A if the pressure at B must be 50 psig?

    2. Relevant equations

    PA/ρg + VA2/2g + ZA = PB/ρg + VB2/2g + ZB + hf
    Since, VA = VB and ZA=0, Bernoulli equation can be simplified to:

    PA/ρg = PB/ρg + ZB + hf

    3. The attempt at a solution

    I am stuck at this point if anyone can help I would greatly appreciate it

    For Bernoulli you need V, so how would you go about finding V? If you had v you'd be home free, no?

    (I assume 6" pipe means 6" diameter. And watch out for p given you as "psig").
