Chapter 5, Problem 5.101(choose chapter or problem)
Figure P5.101 shows a test rig for evaluating the loss coefficient, K, for a valve. Mechanical energy losses in valves aremodeled by the equation:ghL = K(V22 ),where ghL is the mechanical energy loss and V is the flow velocityentering the valve. In a particular test, the pressure gage reads40 kPa, gage, and the 1.5-m3 catch tank fills in 2 min 55 s.Calculate the loss coefficient for a water temperature of 20 C.
