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?

A pump is being used to transport a liquid food product (density = 1000 Kg/m3, viscosity= 1.2 x 10 -3 Pa-s) from a holding tank to a filling machine at a mass flow rate of 2 Kg/s. The liquid level at the holding tank is 5 m above the pump, and the filling machine is 10 m above the pump. There is 100 m of 2 inch nominal diameter sanitary pipeline (assume: commercial steel) between the holding tank and the filling machine with one open glove valve and three medium sweep 90oelbows in the system. Determine the theoretical power requirement of the pump if the efficiency is 75%. Answer: 234 Watts. Show the solution.

A pipe joins two reservoirs whose head difference is 10m. The pipe is 0.2 m diameter, 1000m in length and has a f value of 0.008. (a) What is the flow in the pipeline? (b) It is required to increase the flow to the downstream reservoir by 30%. This is to be done adding a second pipe of the same diameter that connects at some point along the old pipe and runs down to the lower reservoir. Assuming the diameter and the friction factor are the same as the old pipe, how long should the new pipe be? 10m Original pipe New pipe 1000m
State clearly your assumptions in your solution sheet
Suppose the pump as shown in the figure is operating at free delivery conditions. The pipe, both upstream and downstream of the pump, has an inner diameter of 2.0 cm and nearly zero roughness. The minor loss coefficient associated with the sharp inlet is 0.50, each valve has a minor loss coefficient of 2.4, and each of the three elbows has a minor loss coefficient of 0.90. The contraction at the exit reduces the diameter by a factor of 0.60 (60% of the pipe diameter), and the minor loss coefficient of the contraction is 0.15. Note that this minor loss coefficient is based on the average exit velocity, not the average velocity through the pipe itself. The total length of pipe is 8.75 m, and the elevation difference is (z1 - z) = 4.6 m. The pump's performance follows a parabolic curve fit, Havailable = H, - aV where Ho = 19.8 m is the pump's shutoff head, and a = 0.00426 m/(Lpm)2 is a coefficient of the curve fit. Estimate the operating volume flow rate V in Lpm (liters per minute). The…
