After running the lab, you select an analysis point with the following properties: Atmospheric Pressure: 14.7...
If you could show all work with explanations that would be great!! Thanks!! #2. (30 pts) A turbocharger boosts the inlet air pressure to an automobile engine. It consists of an exhaust gas-driven turbine directly connected to an air compressor, as shown in a below figure. For a certain engine load, the conditions are given in the below figure. Assume that both the turbine and the compressor are reversible and adiabatic, having also the same mass flow rate. Engine power...
Problem 1 - Gas Turbine Engine. Assume the gas turbine engine operates on basic non-ideal Brayton cycle with the following specifications Inlet Condition: Dry air at 537 R and 14.7 psia Pressure Ratio: 24.2 Actual Exhaust Temperature: 950 F Compressor and Turbine Efficiency: 85% Actual Power Output 34 MW Using given/assumed values, determine: a) firing temperature, b) cycle efficiency, c) air mass flow rate. Problem 2- HRSG. Assume the HRSG is used to produce saturated steam at 600 psia using...
A compressor works on a pressure of 105 kPa and temperature 300 K in a Brayton cycle and has an efficiency of 45%. The exhaust temperature is 700 K. Find the pressure ratio and the specific heat addition by the combustion for this cycle. The inlet pressure of an air compressor is 100 kPa, with temperature 290 K, and brings it to 600 kPa, after which the air is cooled in an intercooler to 330K by heat transfer to the...
Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
The solution belongs to the 1st question, i need the solution for the 2nd question. 1. A single cylinder 1.6 lt, spark ignition engine is operating on the ideal Otto cycle at a compression ratio of 9. The ambient air around the engine is at 1 bar and 20 °C and the fuel consumption of the engine is 13 L/h gasoline at 5600 rpm. Evaluate a. The highest pressure and temperature in the cylinder throughout the cycle b. Net work...
C) Axial-flow compressor Answer 3) Specifie speed (0.) for the compressor compressor should selected? application is 0.9. Which of the following type of 52 th Reciprocating compressor B) none of these A) Centrifug al compressor 1,) compressor D) Centrifugal fan 6) &7) The compressor is tested at sea level on a stationary atmospheric temperature and pressure is design operating point, the mass flow rate through the compr rotational speed is 7000 rpm. Determine the flow compressor is operating at the...
The Boeing 747 has a cruising altitude of 45,000 feet and cruising speed of 275 m/s. At this elevation, the temperature and pressure according to the US Standard Atmosphere (air properties as a function of altitude) are 220K and 1.8x104 Pa, respectively. The engines are steady state devices that can be modeled using the 1st Law of Thermodynamics with air (ideal gas) as the working fluid undergoing several processes. a. The inlet area of the engines is 0.5 m2. What...
