Consider a wing mounted in the test-section of a subsonic wind tunnel. The velocity of the airflow is 160 ft/s, and the velocity at a point on the wing is 293 ft/s.

If the test-section air temperature is 510°R and the flow velocity is increased to 450 ft/s, what is the pressure coefficient at the same point?

(Round the final answer to three decimal places.)

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.
