Water flows through a Parshall flume at a rate of 47.8ft3/s. The throat width is 4.0ft. Calculate the flume upstream head in feet?

Calculate the flume upper head in a Parshall flume with a throat width of 1.5ft for a flow of 5.56ft3/s?

A pitot-static tube is mounted on an airplane to measure airspeed. At an altitude of 10000ft, where the temperature is 23°F and the pressure is 10psia, a pressure difference corresponding to 10in. of water is measured. What is the airspeed? Water and air properties at 23°F are given: HO2 = 62.4lb/ft3;  Rair =1716J/kg K?
