Diesel Cycle: 15. A Diesel Cycle has a cut-off ratio of 2.5 and the volume at the beginning of Heat addition is 0.05 m3/kg. Find the efficiency of the cycle if the net work of the cycle and mean effective pressure is 900 KJ/KG and 950 KPa respectively.

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

The compression ratio of an Otto cycle is 8, at the beginning of the zanthropic compression process, the pressure of the air is 100 kPa, the temperature is 27 "C, the volume is 550 cm. At the end of the lzantropic expansion process, the temperature of the air is 700 K. Using the specific temperature values ​​at room temperature (according to the cold air standard assumptions) Find the gravity of the air.

Pls answer thank you! The following data were obtained during performance test with a simple open cycle gas turbine engine: compressor inlet temperature, 520*R: compressor isentropic discharge temperature, 672"R: actual compressor discharge temperature, 691"R: turbine inlet temperature, 1500 R: turbine isentropic discharge temperature. 1184"R: and turbine actual discharge temperature, 1216°R. For these conditions calculate the thermal efficiency in percent.

Need answer please. Carefull solution to solve for the correct answer thank you.

The Fifth Question: A six-cylinder, 4-stroke petrol engine develops 62 H.P at 3000 r.p.m. The volumetric efficiency at N.T.P. is 85%. The bore is equal to the stroke and thermal efficiency of 25 % may be assumed. Calorific value of petrol is 44100 kj/kg. Air-fuel ratio is to be 15:1. Calculate the cylinder bore and stroke.

Ali Khaleel Kareem O Homework Example 2: 2.6 (Page 45) In a stream power plant, the steam mass flow rate is 80ton/h, the steam inters the turbine at 6MPA and 480 °C, condenser pressure = 0.06MPA, mechanical and electrical efficiencies are 0.96 & 0.95, respectively. Find the specific steam consumption and the power output. Example 3: 2.7 (Page 46) Find the cycle efficiency and specific steam consumption of a reheat cycle (Error! Reference source not found.) operating between pressures of 3MPA and 0.004MPA, with superheat temp of 450 °C. Assume that the first expansion is carried out to the point where the steam is dry saturated and then the steam is reheated to the original superheat temp. The feed pump term may be neglected.

3.1 A 3 liters S.I. V6 engine that operates on a four-stroke of 3000 revolution per minute, the compression ratio is 10, the lengths of the connecting rod and the crank offset are 15 cm and 4 cm respectively, the combustion is completed at 35° of the crankshaft rotation after I need an answer as soon as possible, and I hope it will be clear. Greetings, my bro. TDC, the engine is running with the stoichiometric air-fuel ratio, mechanical efficiency 90%. If the engine is connected to a dynamometer which its reading of 100 kW. Calculate: 1-piston speed at end of the combustion, 2-volume of the combustion chamber at end of the combustion, 3-engine torque, 4- indicated mean effective pressure and 5-break specific fuel consumption.

Please help me
