Anormal shock propagates at 2000 ft/s into the still air in a tube. the temperature and pressure of the air are 80 °f and 14.7 psia before “hit” by the shock. calculate the air temperature, pres- sure, and velocity after the shock, the stagnation temperature and pressure relative to the shock ahead of and behind the shock, and the stagnation temperature and pressure relative to the tube ahead of and behind the shock.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
