A Pitot-static tube is used to measure the velocity of helium in a pipe. The temperature and pressure are 51°F and 26 psia. A water manometer connected to the Pitot-static tube indicates a reading of 2.2 in. (a) Determine the helium velocity. (b) Is it reasonable to consider the flow as incompressible? (a) V = i ft/s (b)
