In the design of a 500m long water pipeline it is proposed to keep head loss, hf, less than 6m for a flow of 0.50 m's1. The pipeline must also be able to withstand water hammer pressures under rapid valve closure condition at the discharge end. Two types of pipes- PVC and steel - each 50 cm in diameter are available. Which pipe will you recommend? 1. The Darcy friction coefficient, 2, can be estimated from Figure 1. The value of the roughness height for steel pipe is 0.00015m, while the PVC pipe can be considered hydraulically smooth. The thickness of each pipe is 1 cm and the Modulus of Elasticity, E, for steel is 200x10° Nm2 and for PVC is 1.7×10®N%?. The Bulk Modulus of Elasticity, K, for water is 2x10°Nm2. The working pressures for the steel and PVC pipes are 2 MPa and 1 MPa respectively. 0,1 0,09|Laminar flow f IN aica Transition 0,08 Laminar Critica! flow Complete turbulence, rough pipes Zone 20ne 0,05 0.07 0,04 0,06 0,03 0,05 0,02 0,015 Lio 0,04 0,01 0.008 Re, 0,006 0,03 0,004…
Water at 25 deg C (998 kg/m 3 ) flows at 10 m 3 /s through a straight pipe of an ID of 1.38 m to 2 m-ID. Consider the level of the entrance and terminal bottom walls of the pipe equal, neglecting the effects of potential energy. In addition, the shaft work is zero. Calculate the pressure drop assuming the pipe is a commercial steel pipe. Suppose there are no friction losses, what is the theoretical pressure drop?
