A pump-pipeline system (shown in the adjacent figure) must deliver water (@ 50 °C) to point 'G' at a pressure of 23 psig. The water flow rate through this system can vary from 15 to 110 USGPM. (Recall that 1 USGPM = 6.31 x 10-5 m³/s.) All of the minor losses in the discharge piping sum to a value of 32.7. The friction factor can be taken to be constant (fD = 0.021). System specifications: Ps= -9.5 psi KL = 32.7 PG = 23 psi Ds = 2.9 in LDG = 100 ft hs = 0 ft S Pump (to be selected by you) DD = DG 1.94 in fD = 0.021 hG = 5 ft (ii) Calculate the NPSH-A at POINT 'S' when Q Control Valve Required: (i) Develop the system resistance curve for the piping system between Point "S" and Point "G" (in SI units): hsys (Q) = A + BQ² = Qmax.

Answer rating: 100% (QA)

To develop the system resistance curve for the piping system between Point S and Point G in SI units we need to calculate the head loss in the system ... View the full answer
