5. Consider a Jet-A fuel drop that is evaporating and burning in a jet engine. We will consider different values of the surrounding air temperature Too (of air that comes from the compressor). For all of the cases the following are held constant: The initial drop diameter The liquid fuel density is do is 40 microns, gas pressure p is 30 atm, 700 kg/m³, The temperature rise due to combustion AT, is 1800 K The fuel heat of vaporization Ah, is 2000 kJ/kg. Fuel boiling temperature T is 473 K The ratio of the gas thermal conductivity to heat capacity λg/ Cp is 0.2 x 104 kg/(m-s) The heat capacity (c) of the gas mixture is 1.5 kJ/kg-K

Where necessary, assume air as an ideal gas and consider R = 287J/(kg.K), Cp = 1005 J/(kg.K), Cv = 718 J/(kg.K).   A nozzle is a device that is used to increase the velocity of a fluidby varying the cross-sectional area. At the last section of a jetengine (Fig Q1.a, section 5), air with a mass flow rate of 50 kg/s ata pressure of 500 kPa and a temperature of 600 K enters a nozzlewith an inlet cross-sectional area of 5 m2. The exit area of thenozzle is 20% of its inlet area. The air leaves the nozzle at avelocity of 300 m/s. The nozzle is not well-insulated and duringthis process, 5 kJ/kg heat is lost. (iv) Determine the temperature of the air as it leaves the nozzle.(v) Calculate the pressure of the air as it leaves the nozzle.

Two moles of an ideal diatomic gas is taken through the cycle shown. At the state 1, the pressure is P1 and the volume is V. If p =300 kPa and V, = 040 m', find p2, P3 and T3- Also compute W, Q. AE per cycle, and the thermal efficiency n. int isothermal Adiabatic Vị 3V1 Volume Pressure

Please answer c A supersonic converging-diverging nozzle is near the exit of a turbojet engine. Its cross-section is circular. The gas has the properties of air, and the flow is isentropic. At the throat location (the minimum area) the air flow is choked (is Mach one) and the throat has diameter of 20 cm.

Please Solve only if you are 100% Sure , Don't make any kind of Mistake. Show all the work ,if possible attach Steam Table. 1)what is the state of steam at 623 K and 90 bar pressure? Determine the specfic entropy of this steam

The values of Cp for the consu Ammonia in air is a toxic mixture when the ammonia is 0.45% by volume. Calculate how much leakage from an ammonia compressor can be tolerated per 1000m³ of space. The pressure is 1bas and the temperature is 15 °C. The molar mass of ammonia (NH3) is 17kg/kmol, and it may assume to act as a perfect gas in this case. and 70 °C. The vessel is A perfect insulated vessel having three compartments A, B and C of volume 1.3m³, 1.2 m³ and 1.0 m² respectively are separated from each other by thin membrane. Compartment A is filled with ritrogen having a pressure 3bar, at a temperature 25 °C, compartment B is filled with hydrogen having a pressure of 20bar at a temperature -40 °C and compartment C filled with carbon (IV) oxide at a temperature 175 °C and pressure 6bar. If the thin membrane are punctured and the three gases allowed to mix freely, calculate: (i) The final temperature of the mixture The final pressure of the mixture (iii) The change in entropy of the…
