What is the difference between the pressure head at the end of a150m long pipe of diameter 1m coming from the bottom of a reservoirwith a water surface 40m above a receiving reservoir delivering10m3s-1; and water coming through an identical route in an openrectangular channel of width 1m with the same delivery. Assume thatthe Darcey Weisbach friction factor is 0.0019 and that the Manningn for the channel is 0.013.
