Chapter 10, Problem 10.5P
A capacitance pressure transducer is used to measure the pressure differential across an orifice meter located in a 25.4-cm pipe. For air flowing at 32 °C, if the pressure differential is 69 kPa, find the pressure head in cm H2O.

A pitot tube is inserted into an air flow to measure the flow speed to measure flow speed. The Pitot tube is inserted into a 100mm diameter tube so that it points upstream into the flow and the pressure as show in figure 5 where p0 = stagnation point. The static pressure is measured at the same location in the flow, using a U-tube differential manometer. Consider density of air equal to 2.3kg/m3 and determine the air flow rate.
Example 3.8.In Example 3.7 we considered a vacuum system with zero leaks. No real vacuum systems aretotally leak-free; engineers work very hard to keep the leakage rate as low as possible. If thetank in Example 3.7 has a leak of 0.0001 lbm/min of air, what will the pressure-time plot looklike, and what will be the final pressure?

A 3.81-cm diameter venturi meter is installed in a pipe with an internal diameter of 10.23 cm. A 127 cm manometer filled with mercury is used to measure the pressure difference across the venturi meter. If the manometer reads 101.6 cm when 15 °C water is flowing through the pipe, what is the flow rate of water (m3/min)? Assume that the venturi meter coefficient of discharge equals 0.98.
