- Explain and contrast the functionality of a steam turbine and gas turbine engine. Sketch the main working parts, label them, and describe their functionality. Sketch a marine boiler system, describe its functionality, and label the main components.. Suppose someone wants you to invest money in anautomobile engine, claiming that it will produce moreenergy than is found in the fuel used to run it. Whatwould be your response? Explain.A steam Carnot engine operates between 350°C and 120°C. The net power output is 450 kW. Calculate the efficiency of the cycle, the heat input and the mass flow rate of the steam. What power is required to drive the pump? [37%, 1218.9 kW, 1.37 kg/s, 386.5MW] 9.
- I need help on this assignment: Design a steam cycle that can achieve a cycle efficiency of at least 40% under the conditions that all turbines have isentropic efficiencies of 85%, and all pumps have isentropic efficiencies of 60%. Prepare an engineering report describing your design. This must include the following: (a) Discussion of various cycles attempted to meet the goal as well as the positive and negative aspects of your design.(b) System figures and T-s diagrams with labelled sates and temperature, pressure, enthalpy and entropy information for your design. (c) Provide calculations for above4. The efficiency of an Otto cycle is 50% and y is 1.5. What is the compression ratio ? [Ans. 4]The thermal efficiency of the Brayton cycle is 36%. What is the turbine heat rate that fulfills this cycle, complete with units?
- What is the engineering responsibility in designing a power plant ensuring public safety, which uses fuel that is directly responsible for global warming? How might these responsibilities be fulfilled simultaneously? (Hint: Evaluate the engineering responsibility to public safety and environment in the development of new power plant)2.) A four-cylinder, two-stroke cycle diesel engine with 10.9 cm bore and 12.6 cm stroke produces 88 kW of brake power at 2000 RPM. Compression ratio rc = %3D 18:1. (a) engine displacement in cm³, (b) brake mean effective pressure in kPa, (c) torque in N-m, (d) clearance volume of one cylinder in cm³.Please answer this question. Thank you very much. also handwritten thank you
- Using thermodynamicsExample dulmalek Air enters the compressor of an ideal air-standard Brayton cycle at 300K. the compressor ratio is 8 and the turbine inlet temperature is 1300K. Determine: a) The gas temperature at the exit of the compressor and the turbine. b) The back work ratio. c) c) The thermal efficiency. Assume the compressor efficiency of 80 percent and the turbine efficiency of 85 percent. d) The thermal efficiency of the gas-turbine power plant if generation having an effectiveness of 80 percent is installed. ShayOut of hydropower and solar power, which one would be cheaper in the long run, in terms of production and distribution. Why?
