P2 B L Open to atmosphere A P1 A liquid flows through a piping system from P1 to the top of a structure at P2 Sections A and B are 2 sch 40 pipe The pump suction piping is 2 sch 40 pipe AND CAN BE ASSUMED FRICTIONLESS Section C is 1.5 sch 40 pipe The piping system is intended to provide liquid at a rate of 40 gpm while maintaining a P2 pressure of 3 psig. The flowrate at P1 and P2 are the same. (ie.. there is no splitting or branching of the flow) The friction factor, f (fanning), can be assumed to be 0.008 The pump efficiency can be assumed to be 37% Given: . The density of water is 62.4 lbm/ft3 . The specific gravity of the fluid is 0.7 The viscosity of the fluid is 15 CP . The vapor pressure of the fluid is 3 psia The piping system dimensions are as follows: A=18ft ; B=190ft ; C=60ft ; L=20ft A and B section C section fitting type fitting K value number of fittings number of fittings 90 degree bend 10 f 7 8 gate valve 8f 5 7 check valve 21 f 2 tee (run) 16 f 2 5 tee (branch) 44 f. 3 1 reducer K1=0.5*(1-8-2)^2 1 NOTE: B = (smaller flow diameter)/(larger flow diameter) = What is the volumetric flow, ft3/s, through the pipe?.08913 What is the velocity in sections A and B, ft/s? 3.825 What is the velocity in section C, ft/s 6.304 What is the pressure at P1, psig? -6.067 For the next 4 questions, do not include the pressure drop due to elevation changes What is the pressure drop, psi, due to pipe in sections A + B? What is the pressure drop, psi, due to pipe in section C? What is the pressure drop, psi, due to the pipe and fittings in sections A-B? What is the pressure drop, psi, due to the pipe and fittings in section C? What is the pressure drop, psi, due to the elevation change from P1 to P2? What is the required TDH, ft, of the pump? What is the NPSHA, net positive suction head available, ft, for the pump? What is the required hydraulic horsepower, hp? What is the BHP, brake horsepower, of the pump? In order to select a pump for this system, the system curve must be solved for serveral additional flowrates. With this in mind, what is the TDH, ft, required when the pump is running and 0 gpm if flowing through the system? Check Part
