Question

2. Select the pump speed with the highest efficiency from the pump I chart as shown based on the flowing conditions. A 1200 m-long (25-cm) diameter) pipeline connects two reservoirs with an elevation difference of 32 m. Minor losses include entrance, exit, and a globe valve ($K_v$=10). Assume f=0.02, determine the operating flow rate, pump head, and efficiency for the pump.

Step 1

From the given information, we know that the pipeline is 1200 m long with a diameter of 25 cm. We can use the Darcy-Weisbach equation to calculate the flow rate: Q = (π/4) * D^2 * V where Q is the flow rate, D is the diameter, and V is the velocity. To find the Show more…
