SQ 5.1     Calculate the Mach number of an object traveling at 735 mph at 10,000 feet above sea level? The speed of sound at 10,000 feet is 734.5 mph.
SQ 5.2     To distinguish between compressible and incompressible flow in gases, the Mach number must be greater than about _____.
SQ 5.3     Water flowing through a 1” pipe at 25 psi and a speed of 0.87 ft/sec increases up to a 1.5” pipe and discharges into an open tank 10 ft. above. What is the flow velocity and the pressure in the pipe at the discharge point? Assume no branch pipe and ignore viscosity and pressure losses.
