A generator on a research aircraft requires 0.2 slugs per second of cooling
air. A cooling air scoop for the generator is designed to be operated while the
aircraft is cruising at 200 mph at 20,000 ft above sea level in standard atmospheric
conditions. The scoop connects to an opening on the generator casing that has an
area of 2 ft2
. Determine the required area of the inlet of the scoop. Also determine
the air velocities and pressures at the scoop inlet and at the connection with the
generator casing.
--SHOW THE ILLUSTRATION AND A COMPLETE SOLUTION--A motorist equips his automobile tires with a relief type valve so that the pressure inside the tire never will exceed 240 kpa gage. He starts the trip with a pressure of 200 kPa gage and a temperature of 23oC in the tires. During the long drive, the temperature of the air in the tires reaches 83oC in the tires. Each tires contains 0.11kg of air. Determine (a) the mass of air escaping each tire (b) pressure of the tire when the temperature returns to 23oC.
An air compressor delivers 10 ft3of air at a pressure of 130 psia and 85°F into an air reservoir.Calculate the mass of air delivered (lbm).
