Question: A liquid flows through a piping system from P 1 to the top of a structure at P 2 Sections A and B are 2

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 50gpm
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 0.007
The pump efficiency can be assumed to be 37%
Given:
The density of water is 62.4lbmft3
The specific gravity of the fluid is 0.85
The viscosity of the fluid is 10CP
The vapor pressure of the fluid is 5 psia
The piping system dimensions are as follows: A=15ft; B=215ft; C=70ft; L=16ft
\table[[,,A and B section,C section],[fitting_type,fitting K? value,number of fittings,number of fittings],[90 degree bend,7f,5,5],[gate valve,8f,7,9],[check valve,23f,2,1],[tee (run),16f,4,5],[tee (branch),60f,4,2],[reducer,K1=0.5**(1-2)2,,1]]
NOTE: =(smaller flow diameter)/(larger flow diameter)
What is the volumetric flow, ft3s, through the pipe:
What is the velocity in sections A and B,fts?
What is the velocity in section C,fts?
What is the pressure at P1, psig?
For the next 4 questions, do not include the pressure dron 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, hoi.
