A vertical force P acting on the 2.5-lb cylindrical valve A, shown in section, serves to limit the flow of fresh water from the top of the vertical pipe B of 3-in. inside diameter. Water is fed through the bottom inlet of the pipe. Calculate the force P required to maintain the valve in the position shown under a flow rate of 600 gal /min and a static pressure of 12 lb/in.² in the water at section C. Recall that 1 gal contains 231 in.
