N. 8 Thermodynamics property tables are allowed. Assume any necessary assumptions. 1.a) Consider subsonic flow in a converging nozzle with fixed inlet conditions. What is the pressure, and (c) the backpressure to the critical pressure on $$(a)$$ the exit velocity, $$(b)$$ the exit I-b) Air enters a nozzle at $$0.2\mathrm{MPa},350\mathrm{K}$$, and a velocity of $$150\mathrm{m}/\mathrm{s}$$. Assuming isentropic flow, determine the pressure and temperature of air at a location where the air velocity equals the speed of sound? (6 Marks)
