A fixed-area internal compression inlet has a capture/throat area ratio Ac/At of 1.2. Determine the following: a) The Mach number at which the inlet will start b) The Mach number at the throat after starting c) The pd of the inlet after starting with the shock at the throat d) The Mach number at which the inlet will unstart

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.
