A pitot tube directed into a water stream having a velocity of 2.7 m/sec. It has gauge difference of 30 mm on the water mercury manometer. Find its coefficient.
35 + 9.81 (0.3824 - 7-2) = - 49.54 kPa. S. Chand e oladall i.e.Pg =- 49.54 kPa. This shows that the given pressure at A, 35 kPa is gauge pressure and hence there is vacuum at point B. (Ans.) Example 6.5. An open circuit wind tunnel draws in air from the atmosphere through a well contoured nozzle. In the test section, where the flow is straight and nearly uniform, a static pressure tap is drilled into the tunnel wall. A manometer connected to the tap shows that the static pressure within the tunnel is 45 mm of water below atmosphere. Assume that air is incompressible and at pressure is 100 kPa (absolute). Calculate the velocity in the wind tunnel section (Refer to Fig. 6.6). Density of P.= 100 kPa water is 999 kg/m' and characteristic gas constant for V =0 air is 287 J/kg K. ساP حقوق النشر 25°C, Test section = 25°C (GATE)

The water tower is closed but there is a section of air that is atmospheric pressure just above the water. The corsss ectional area at point 2 is 4.75 x 10 m. The cross sectional area fot the water tower is very large. What is the speed of the water coming out of the pipe at point 2? (density of water = kg/m³) 3.

A fan is used to blow air (density=1.15 kg/m3) in a duct. A pitot tube is placed in the duct as shown. The static pressure in the duct is measured with a wall tap and pressure gage. Use the gage readings to determine the velocity of the air. note: Pitot tube is used to measure the air total pressure.
