Oxygen is flowing through a nominal 2 inch schedule 40 steel pipe pipe at a velocity of 10 ft/s. The oxygen is at a fairly constant pressure of 50 psia and at a temperature of 90 deg F. (there would be some pressure drop in the pipe as the oxygen flows along but we will ignore this and assume that at the point where we measure the velocity, the pressure and temperature are also measured) What is the mass flow rate of oxygen in lbm/s? Note that the inside diameter of a nominal 2 inch schedule 40 steel pipe is 2.067inches. Assume ideal gas principles apply.
The airspeed of an aeroplane is measured with a Pitot tube. The plane is flying at an altitude of 10000m, and the Pitot tube measures a gauge pressure of p = 10kPa. What is the airspeed of the plane?
