Water at a density of 62.4 lbm/ft and a pressure of 132 psi is flowing through a pipe at 20 ft/sec. The speed of sound in the water is 4782 ft/sec. A check valve suddenly closed. Given: Pmax = AP spike Pstatic AP spike = Pc AV 9c = fluid density Pe = AV change in fluid velocity Ibm ft 9c gravitational constant = 32.17 lbf sec What is the maximum pressure of the fluid in psi? 1610.5 1420.3 1026.8 1160.6
