The converging-diverging nozzle of the engine of a new supersonic unmanned aerial vehicle (UAV) has an exit area of 50 cm^2 . At the design operating condition, the mass flow rate of exhaust gases (? ≈ 1.4, molecular weight = 26 g/mol) is 1.75 kg/s. The exhaust gases enter the nozzle with stagnation pressure and temperature equal to Po = 300 kPa and To = 500 K, respectively a) What is the optimal cruising altitude for the operation of the nozzle of this UAV? (b) What is the lowest altitude at which the plane can fly such that the flow inside the diverging part of the nozzle is kept supersonic? Note: - Assume that the stagnation conditions of the flow of exhaust gases entering the nozzle are kept constant with varying altitude

A gas flows steadily through a rotary compressor at a temperature of 16 ⁰C, a pressure of 100kPa, and an enthalpy of 392.2 kJkg-1. The gas leaves the compressor at a temperature of 245⁰C, a pressure of 0.6 MPa and an enthalpy of 534.5 kJkg-1. There is no heat transfer to or fromthe gas as it flows through the compressor. Using the steady flow equation appropriate toeach case, evaluate the external work done per unit mass of gas: a) when the inlet and exit velocities of the gas are negligible b) when the inlet velocity of the gas is 80 ms-1 and the exit velocity of the gas is 160 ms-1.
