Question: please solve the following steps. pump draws water from a sump and delivers it to an open tank through 210 ft of 2-in schedule 40
1) Setup the generalized energy equation between a point on the surface of the water in the sump (Elev 24ft ) and a point at the inlet of the pump (Elev 28.62ft ). Solve for the pressure head at the inlet. Include entrance losses, friction from the 5 feet of straight pipe, and minor losses from the foot valve and elbow. 2) Find the stagnation pressure at the inlet of the pump and compute the NPSHA. 3) Setup the generalized energy equation between a point on the surface of the water in the sump (Elev 24ft ) and a point at the surface of the tank (Ele 159ft ). Solve for the required head on the pump, hp. In addition to the losses in step one also include exit loss, friction from the 210 feet of straight pipe, and minor losses from the two elbows, check valve and gate valve located in the discharge line. 1) Setup the generalized energy equation between a point on the surface of the water in the sump (Elev 24ft ) and a point at the inlet of the pump (Elev 28.62ft ).
