1. Two nozzles, shown in the sketch below, connect a large reservoir of compressed air to a large room at ambient pressure (1 atm) and ambient temperature (23 C). The nozzles are very far apart and do not interact. Note the dimensions stated in the sketch. (a) For a supply pressure of 3.0 atm mark the correct statement and show why each one is correct or not. [10] Nozzle A delivers larger mass flow rate Nozzle B delivers larger mass flow rate Both nozzles deliver the same mass flow rate (b) Also, for a supply pressure of 3.0 atm mark all correct statements and show why each one is correct or not. [15] The Mach number at the exit of Nozzle B is larger than that for Nozzle A. The flow at the exit of Nozzle B is supersonic The pressure at the exit of Nozzle B is 1 atm The flow within both nozzles is isentropic The pressure at the inlet of Nozzle A is higher than 3.0 atm (c) For each nozzle, sketch the flow features inside the nozzle and in the exhaust plume.
