uppose the pump of Fig. P14–23 is operating atfree delivery conditions. The pipe, both upstream and downstreamof the pump, has an inner diameter of 2.0 cm andnearly zero roughness. The minor loss coefficient associatedwith the sharp inlet is 0.50, each valve has a minor loss coefficientof 2.4, and each of the three elbows has a minor losscoefficient of 0.90. The contraction at the exit reduces thediameter by a factor of 0.60 (60% of the pipe diameter), andthe minor loss coefficient of the contraction is 0.15. Note thatthis minor loss coefficient is based on the average exit velocity,not the average velocity
Suppose the pump of Fig. P14–23 is operating atfree delivery conditions. The pipe, both upstream and downstreamof the pump, has an inner diameter of 2.0 cm andnearly zero roughness. The minor loss coefficient associatedwith the sharp inlet is 0.50, each valve has a minor loss coefficientof 2.4, and each of the three elbows has a minor losscoefficient of 0.90. The contraction at the exit reduces thediameter by a factor of 0.60 (60% of the pipe diameter), andthe minor loss coefficient of the contraction is 0.15. Note thatthis minor loss coefficient is based on the average exit velocity,not the average velocity through the pipe itself. The total length of pipe is 6.7 m, and the elevation difference is (z1 - z2)= 4.6 m. Estimate the volume flow rate through this pipingsystem.
