Describe the various types of compression system commonly found in gas turbines engines. What are the requirements of the compressor? Under what circumstances would you use each type of compressor

Required information Problem 09.015 - 3-Step Air-Standard Cycle with Constant Specific Heats - DEPENDENT MULTI-PART PROBLEM - ASSIGN ALL PARTS An air-standard cycle with constant specific heats at room temperature is executed in a closed system with 0.003 kg of air and consists of the following three processes: 1-2 v= Constant heat addition from 95 kPa and 17°C to 380 kPa 2-3 Isentropic expansion to 95 kPa 3-1 P = Constant heat rejection to initial state The properties of air at room temperature are cp = 1.005 kJ/kg-K, cy= 0.718 kJ/kg-K, and k = 1.4. Problem 09.015.b - Net Work for Constant Heat Capacity Air-Standard Cycle Calculate the net work per cycle, in kJ. (You must provide an answer before moving on to the next part.) The net work per cycle is kJ.

The pressure and temperature at the beginning of compression of an air-standard Diesel cycle are 80 kPa and 300 K, respectively. At the end of the heat addition, the pressure is 6821 kPa and the temperature is 2150 K. (a) Determine the compression ratio. r = (b) Cutoff Ratio (c) Thermal Efficiency (d) Mean Effective Pressure

What are the main reasons for running jet engines at high temperatures? Select one or more: a. Increased fuel burn b. Greater thermal creep c. Increased efficiency d. Higher thrust e. Decreased noise
