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 25°C, pressure is 100 kPa (absolute). Calculate the velocity in the wind tunnel section (Refer to Fig. 6.6). Density of Po-100 kPa water is 999 kg/m' and characteristic gas constant for V=0 Test section 1-25°C air is 287 lka K (GATE)

Q1: A water tower is an elevated structure supporting a water tank constructed at a height sufficient to pressurize a distribution system for potable water. A completely filled and pressurized water tank was found with a small leakage (a hole 5cm in diameter) located on the sidewall of the tank, around 5 meters below the top of the tank. Please calculate the velocity of leakage water that discharges to the normal atmosphere. The dimension of the tank is 20-meter in height and 10-meter in diameter. The gauge pressure of the water tank top is 0.1M Pa. The Bernoulli equation is: P₁/pg + V₁²/2g +h₁ = P₂/pg + V₂²/2g +h₂ Gauge Pressure: 0.1 M Pa 5 meters Leakage velocity?

42. 4.4. Measurement of airflow shows the static and stagnation pressures to be 30 and 32 psig, respectively. (Note that these are gage pressures.) Assume that pamb = 14.7 psia and the temperature is 120F. (a) Find the flow velocity using equation (4.21).

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.
