Assume, first, that the valve (V) is closed;no water will then be flowing through the pipe and all ofthe various pressure gauges will indicate the same pressurein the pipe. Assume, as a second condition, that the valve (V)is partly opened; there will… … Fig. 2 valve still more will, increase the flow of water and alsothe difference in indications of the various gauges. If thegauge (Gg) at the end of the pipe indicates zero pressure,it is apparent that the total pressure supplied by the pumphas all been used in forcing the water through the pipe.…
