- Please show your complete solution. Thank you! Air flows in a steady flow manner through a converging tube. At the inlet the pressure is 690kPaabs and the density is 0.838 kg/cu.m. If air enters with a volume flow of 125 cu.m per min at the rate of 94 m/min and the exit section has a diameter of 350mm, determine a.) the mass flow rate, kg/min b.) the diameter of the entrance section and c.) the exit velocity. Assume that the density is constant.A compressed Air enters a convergent-divergent nozzle, at 4.0 atm, 300 K and at Mach 2.0. The nozzle is fitted at the exit of a 0.3 m constant diameter pipe and 2.0 m long that supplies the air. Assuming that the friction factor for the pipe is 0.003, and that a normal shock occurs in the pipe at Mach number 1.8, a) Find the length of the pipe between the location of the normal shock and the inlet of the nozzle. b) Claculate the throat and the exit plane diameters of the nozzle if the mach number at the exit plane is 2.0 c) Calculate the exit pressure. d) On a graph, skecth the variation of static and stagnation pressure along the pipe and the nozzle.A converging–diverging nozzle exits smoothly to sealevelstandard atmosphere. It is supplied by a 40-m3 tankinitially at 800 kPa and 100 °C. Assuming isentropicflow in the nozzle, estimate (a) the throat area and(b) the tank pressure after 10 s of operation. The exitarea is 10 cm2.
