Question 3. Compressed air stored at ambient temperature is used as part of a cooling system. A nozzle, with an exit area of 22 mm2 delivers the air. Air is to be delivered into a change with ambient pressure of 1020 mbar. For adequate coooling the air needs to be delivered at -28 C and 9.0 g/s. Determine what the bottle pressure should be, to 2 decimal places, in bar. Question 3. Compressed air stored at ambient temperature is used as part of a cooling system.
