Unformatted text preview: o F) 4. (2 points) Comparing the case of problem 3, calculate the percentage change in the total weight of air in the room when the temperature is reduced to 10 o F, assuming that the pressure remains the same. 5. (3 points) An F22 supersonic fighter aircraft is in a rapid decent. At the instant it passes through a standard altitude of 35,000 ft, its time rate of change of altitude is 600 ft/s. Corresponding to this rate of decent at 35,000 ft, is a time rate of change of ambient pressure. Calculate this rate of change of pressure in units of pounds per square foot per second....
