    pump curves

    I am performing a field test of the pumps at our water treatment facility. While I know it is necessary for the pressure guage to be located between the throttling valve and the pump, is it necessary for the meter to be in the same area as the pressure gauge? The flow does not empty to...

    plotting pump curves

    The comment about getting nervous about blowing something up I'm sure is in jest but it doesn't make me warm and fuzzy. The low lift pumps operate under an existing head that is reasonably easy to figure out. The high lifts pump to a distribution system with tanks and pressure zones attributed...

    plotting pump curves

    I have been asked to plot pump curves for three 125 horsepower pumps that are presently installed at our water treatment facility. The pumps are 1-stage VARIABLE FREQUENCY DRIVE vertical turbine pumps. We have the pump curves from when they were installed but would like to plot the present day...

    Pressure in Pipe/ data from hydrant flow tests

    Hydrae, I am using a pitot tube and I have used the equation Q=29.83*c*d^2*(p^.5). Then you mentioned the manipulated HZ equation in your first response and that was the equation I needed to proceed. Thank you so much for your help. 199292

    Pressure in Pipe/ data from hydrant flow tests

    It has been a while since I have had to interpret the results from a hydrant flow test using a pitot tube. For example I have the results of the static pressure to be 110 psi and the residual to be 75 psi. From this I assume I plug these numbers into the V=[2((110-75)*144)]/62.4 in order to get...
