Find the loss in total pressure for each run in the simple duct system of Fig. 1, using the equal-friction method and in English unit. The total pressure available for the duct system is 0.12 in. wg (30 Pa), and the loss in total pressure for each diffuser at the specified flow rate is 0.02 in. wg (5 Pa). Duct fittings are listed in Table 1. Assume the duct dimeter in run 1 is 10 in. and the rest are 8 in.

Q1/ liquid is pumped from a ground level reservoir to an overhead tank through a 5 cm ID pipe as shown in Fig. (1): i. What pressure developed by the pump to 45° elbow 8 m Fig. (1) Globe valve Tank 5 m supply water to the tank at the rate of 245 I/min? ii. What is the power required for the pump, if the pump is only 62% efficient? iii. Calculate the available NPSH. If the pump required 12 m NPSH is it suitable to prevent cavitation for this system? why?

4) Air at 200°F flows through a pipe with 0.5 inch diameter at a rate of 0.08 Ibm/s. What is the flow regime? What would be the corresponding entrance length?
4- A centrifugal pump was tested for cavitation initiation. Total head was 40 m and flow rate were 0.06 m/s. Cavitation started when the total head at the suction side was 3 m. The atmospheric pressure was 760 mm Hg and the vapor pressure at this temperature was 2 kPa. It was proposed to install the pump where the atmospheric pressure is 700 mm Hg and the vapor pressure at the location temperature is 1 kPa. If the pump develops the same total head and flow, can the pump be fixed as the same height as the lab setup? What should be the new height.
Calculate the power supplied to the pump shown if its efficiency is 75%. Water is at 25 degrees Celsius is flowing at the rate of 50.0 m3/h. The suction linf is a standard DN 100 Schedule 40 steel pip, 15m long. The total length of DN 50 Schedule 40 steel pipe in the discharge line is 200m. The elbows are tight, the entrance to the pipe is flush and the globe valve is completely open. Draw the line of total and piezometric heights.
