b. Conduct an analysis for a gas turbine combustor using Propane, C3H8, you can assume the product outlet temperature is 1500 K and the air inlet temperature is 650 K on a standard day (25 C) and the fuel enters at ambient temperature.

List the parameters that influence temperature during metal cutting, and explain why and how?

A thin airfoil can be approximated as a flat plate. The airfoil is set at an angle of 10° to an air flow with Mach 2, a temperature of –50°C, and a pressure of 50 kPa. Using linearized theory, find the pressures on the upper and lower surfaces of this wing.

A small research vehicle with a length of 4 ft travels at Mach 15 at altitudes of 100,000 and 250,000 ft. Determine whether, at these two altitudes, the missile is in the continuum, slip, transition, or free molecular flow regimes. It can be assumed that at an altitude of 100,000 ft, the pressure, temperature, and viscosity are 22 psf, 340 R, and 96 × 10?7 lbm/ft-s, respectively, whereas at an altitude of 250,000 ft, they are 0.11 psf, 450 R, and 100 × 10?7 lbm/ft-s, respectively

Consider a compressor in which air enters at 1 bar, 27°C and exits at 3.5 bar, 127°C. The work required is 127 kJ/kg of air flowing through the compressor. Heat transfer between the compressor and environment occurs at 27°C.

Determine

(a) the heat transfer, in kJ/kg

(b) the entropy generation rate, in kJ/kg.K, for the compressor as a control volume

(c) the entropy generation rate, in kJ/kg.K, for the compressor and the surrounding environment

(d) the entropy generation rate, in kJ/kg.K, for the environment alone.

An object of irregular shape has a characteristic length of L = 1 m and is maintained at a uniform surface temperature of T_s = 325 K. It is suspended in an airstream that is at atmospheric pressure (p = 1 atm) and has a velocity of V = 100 m/s and a temperature of T_? = 275 K. The average heat flux from the surface to the air is 12,000 W/m². Referring to the foregoing situation as case 1, consider the following cases and determine whether conditions are analogous to those of case 1. Each case involves an object of the same shape, which is suspended in an airstream in the same manner. Where analogous behavior does exist, determine the corresponding value of the average heat or mass transfer convection coefficient, as appropriate.

(a) The values of T_s, T_?, and p remain the same, but L = 2 m and V = 50 m/s.

(b) The values of T_s and T_? remain the same, but L = 2 m, V = 50 m/s, and p = 0.2 atm.

(c) The surface is coated with a liquid film that evaporates into the air. The entire system is at 300 K, and the diffusion coefficient for the air–vapor mixture is D_AB = 1.12 × 10^?4 m²/s. Also, L = 2 m, V = 50 m/s, and p = 1 atm.

(d) The surface is coated with another liquid film for which D_AB = 1.12 × 10^?4 m²/s, and the system is at 300 K. In this case L = 2 m, V = 250 m/s, and p = 0.2 atm.
