Design the nozzle of a fuel injector, which has to expand 2.5 g/s of methane (R = 518 J/kgK; k=1.31) from p,-9 bar, T,= 300 K, c,~0, down to the pressure p,-3.5 bar. Also, evaluate the flow outlet velocity under design conditions. In off-design operations, the pressure upstream of the nozzle is reduced to p,'=3.9 bar, by keeping the same inlet temperature. The downstream pressure remains constant. Determine, under off-design conditions: The mass-flow rate expanded by the nozzle3B The flow outlet velocity, The produs fou denei
