converging-diverging nozzle exits to sea-level at standard atmospheric conditions. the flow in the nozzle is driven by a 40 m3 compressed gas tank that is initially at 800 kpa and 100 c. estimate the (a) throat area and (b) the tank pressure after 10 seconds of operation. you can assume that the mass flow rate is constant over these 10 seconds. is this a good assumption? the nozzle exit area is 10 cm2
