The pressure rise, AP, across a pump is a function of the fluid density, p, the angular velocity of the impeller, w, the impeller diameter, D, and the volume rate of flow through the pump, V. A model pump is tested using a 5.2 in. impeller diameter at an angular velocity of 115 rad/s. The measured pressure rise as a function of volumetric flow rate is shown in the figure. Use this figure developed for the model pump to predict the pressure rise across a geometrically similar prototype pump at a flowrate of 16.4 ft^3/s. The prototype has an impeller diameter of 11.4 in. and operates at an angular velocity of 210 rad/s. Both pumps operate using water. Report all answers to 3 significant digits.

Learning Goal: To calculate minor head losses and pressure drops for pipe fittings. Minor losses in pipe flow are the result of disruptions to the steady laminar or turblent flow in a pipe by entrances, bends, transitions, valves or other fittings. In general, calculating these losses analytically is too complex. However, all of these losses can be modeled using terms of the form h = KL where Kr, is called the loss coefficient and is determined experimentally. This coefficient relates the minor head loss to the velocity head for the flow. For expansions and contractions, the loss coefficient is calculated using nine the velocity for the smaller diameter pipe. The table below gives some representative values for various minor head losses. These are representative only, and a more complete table would account for different kinds of fittings and connections (like threaded or soldered).
