A converging-diverging nozzle has a throat area of 1 cm2 and an exit area of 4 cm2. The inlet stagnation conditions are Po 500 kPa and To 300 K. The nozzle discharges to an infinite surroundings at Po. The flowing medium is air as a perfect gas with k-1.4 Answer the following: i What are the two isentropic flow solutions for this nozzle with M 1 at the throat? What are the Mach number, P, Po and T, To at...

1. (15 pts) A converging-diverging nozzle has an area ratio of 2, i.e., the exit (or duct) area is 2 times the throat area, which is 80 cm2. The nozzle is supplied from a tank containing air (y 1.4 and R 287 J/kg K) at 100 kPa and 300K. For both cases shown in Fig. , find the maximum mass flow possible through the nozzle and the range of back pressures over which the mass flow can be attained. For...

A nozzle is designed to deliver a supersonic air flow, R = 287 J/Kg/K, of Mach M = 2.19 The reservoir has a pressure of p0 = 648kPa and T0= 300K. The nozzle exit has an area of 0.233 m^2. The nozzle flow exits into an environment that is kept at constant pressure pb which matches the exit pressure of the nozzle. As long as there are no shock waves appearing in – or outside the nozzle, the complete flow...
Air enters an isothermal nozzle at a temperature of 300 K, and a velocity of 10 m/s. The nozzle is very poorly insulated, causing a stray heat transfer rate of 10 kW into the system. The outlet of the nozzle is exposed to an ambient pressure of 1 bar and is choked (Mach = 1). If the area ratio of the nozzle (A, /A2) is 5, what is: The velocity of the nozzle outlet, in [m/s], if the specific heat...

Air flows through a converging-diverging nozzle/diffuser. Assuming isentropic flow, air as an ideal gas, and constant specific heats determine the state at several locations the system. Solve using equations rather than with the tables. Note: The specific heat ratio and gas constant for air are given as k=1.4 and R=0.287 kJ/kg-K respectively. --Given Values-- Inlet Temperature: T1 (K) = 353 Inlet pressure: Pl (kPa) = 546 Inlet Velocity: V1 (m/s) = 61 Area at nozzle inlet: A1 (cm^2) = 7.24...
