Homework : 1- Demonstrate how the rate of air flow in the pipe can be calculated by applying Bernoulli to a flow line from outside the pipe to the inlet of the pipe equalizer. 2- If the used pipe is rough on the inside, will the coefficient of friction be greater? 3- The rate of air flow can be changed in two ways. Exit valve for the compressor or by changing the electrical resistance. Is there a difference between the two methods on the results of this experiment. 4- If there is air leakage from the tube after the pressure gauge places, does that affect the results? 5 - What are the most important sources of error in the experiment, list them in order of importance. 6- Why are there four holes instead of one to measure static pressure in the section?

A centrifugal pump as shown in Figure below has a 100 mm diameter suction pipe and a 75 mm diameter delivery pipe. When discharging 15 L/s of water, the inlet water mercury manometer with one side exposed to the atmosphere recorded a vacuum deflection of 198 mm of Hg; the mercury level on the suction side was 100 mm below the pipe centerline. The delivery pressure gauge, 200 mm above the pump inlet, recorded a pressure of 94.666 Kpa. The measured input power was 3.2 kW. Calculate the pressure at the suction.

1. A pump (Figure 4-07) takes water from a 200-mm suction pipe and delivers it to a 150-mm discharge pipe in which the velocity is 2.5 m/s. At A in the suction pipe, the pressure is -40 kPa. At B in the discharge pipe, which is 2.5 m above A, the pressure is 410 kPa. What horsepower would have to be applied by the pump if there were no frictional losses?
