1. Where necessary, assume air as an ideal gas and consider R = 287 J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K). a) A nozzle is a device that is used to increase the velocity of a fluid by varying the cross-sectional area. At the last section of a jet engine (Fig Q1.a, section 5), air with a mass flow rate of 50 kg/s at a pressure of 500 kPa and a temperature of 600 K enters a nozzle with an inlet cross-sectional area of 5 m2. The exit area of the nozzle is 20% of its inlet area. The air leaves the nozzle at a velocity of 300 m/s. The nozzle is not well-insulated and during this process, 5 kJ/kg heat is lost.Figure Q1.a: Schematic of a Jet engine.(v) Calculate the pressure of the air as it leaves the nozzle.
Assume 2.3 lb/sec of fluid enter a steady-state, steady-flow system with Pi = 105.57 psia, p1 = 0.307 lb/ft^3, v1 = 96.19 fps, u1 = 794.13 BTU/lb, and leave with P2 = 12.97 psia, p2 = 0.13 lb/ft^3, v2 = 431.41 fps, and u2 = 759.71 BTU/lb. During the passage through the open system, each pound rejects 13.2 BTU of heat. Determine the work in hp.

The figure shows data for a portion of the ducting in a ventilation system operating at steady state. The ducts are well insulated and the pressure is very nearly 1 atm throughout. The volumetric flow rate entering at state 2 is AV2 = 4000 ft3/min. Assume the ideal gas model for air with cp = 0.24 Btu/lb·oR and ignore kinetic and potential energy effects. Determine the temperature of the air at the exit, in oF, and the rate of entropy production within the ducts, in Btu/min·oR.

Refrigerant 134a enters an insulated diffuser as a saturated vapor at 80°F with a velocity of 1400 ft/s. The inlet area is 1.4 in?. At the exit, the pressure is 400 lb;/in? and the velocity is negligible. The diffuser operates at steady state and potential energy effects can be neglected. Determine the mass flow rate, in Ib/s, and the exit temperature, in °F.
