Please see all details above and below, and answer all questions.
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 80gpm while maintaining a P2 pressure of 2 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 0.006 The pump efficiency can be assumed to be 39% Given: - The density of water is 62.4lbm/ft3 - The specific gravity of the fluid is 0.8 - The viscosity of the fluid is 25cP - The vapor pressure of the fluid is 6 psia - The piping system dimensions are as follows: A=24ft;B=175ft;C=65ft;L=18ft NOTE: = (smaller flow diameter)/(larger flow diameter) What is the volumetric flow, ft3/s, through the pipe? 0s What is the velocity in sections A and B,ft/s ? 0 What is the velocity in section C,ft/s ? 0s What is the pressure at P1, psig? 0s 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 systemStep by Step Solution
