An ideal gas with k = 1.4 is flowing through a nozzle such that the mach number is 1.6 where the flow area is 70 cm2. approximating the flow as isentropic, determine the flow area at the location where the mach number is 0.8. use data from tables. the flow area at the location where the mach number is 0.8 is cm2.

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.
