1.For a given airplane, compare the power to maintain level flight at a 5000-ft altitude with that at 30,000 ft at the same velocity. Assume drag coefficient remains constant

2.Estimate the power needed to overcome the aerodynamic drag of a person who runs at a rate of 100 yds in 10 s in still air. repeat the calculations if the race is run into a 20-mph headwind: a 20-mph tail wind.

3.Saturated water vapor at 150 deg C is compressed in a reversible steady-flow device to 1000 kPa while its specific volume remains constant. Determine the specfic work required in kJ/kg. The heat transfer is not negligible.
