The performance of the pump on clear water at a given ,speed, and ,flow, is usually known in terms of its tested water performance for the head produced ,and power, consumed. The pump-input ,power, is normally available either as electrical motor driver watts or amps, a measured torque, or even pressures and/or rack position for a diesel engine driver.

Record the time of travel in your record book. Be sure to convert seconds to a decimal portion of a minute ( 20 seconds = 20/60 = 0.33 minutes). Then measure the distance between the flags to determine how far the system has moved. Record the distance traveled in feet in your record book. ,The speed, of travel is ,calculated, using Equation 12.4:
