Water (ρ=998 kg/m³, μ=1.02x10^-3 kg/ms) flows through a 598 m length of pipe with 150 mm in diameter at 60 L/s. Determine the pipe roughness, ɛ if the head loss is 49 m.
A horizontal pipe bend with a deflection angle of 120o has an entrance diameter of 300 mm and exit diameter of 100 mm. Oil with a density of 860 Kg/m3 enters at the rate of 3.6 m/s and at a pressure of 180 KPa. Determine the magnitude of the force required to hold the bend in place for (a) smooth flow; (b) a situation where head loss is 0.05(v100-v300) 2/2g.
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.
