Students did an experiment on Swansea University jet engine. They measured ambient temperature 16 deg C and ambient pressure 1.02 bar, engine RPM 64,664, thrust 17.5781 N, air flow 42.0557 l/s, fuel flow 8.6914 l/h, gauge combustion pressure 0.2942 bar. The temperature values (deg C) at compressor exit, turbine inlet and exhaust were recorded as 39.84, 869.53, 585.93. Assume density of fuel as 0.8 kg/L. The heating value of fuel is 42580 kJ/kg. The idea gas constant R is 0.287 kJ/kg K, the Cp value for air is 1.005 kJ/kg K and the value of specific heat ratio k is 1.4 Estimate the thrust specific fuel consumption value under ideal conditions (g/N-s) Enter your answer to four decimal places in the box below. answer ASAP would be appreciated
We learned that engine design can alter / change engine performance, that by increasing the engine displacement, engine power can be increased. Experts commonly agree that there are three (3) ways to increase the displacement of an engine. Question: 1)Explain the 3 ways of increasing the engine displacement? 2) Explain the commonly used alteration method used by car racers.
you are with your father with his motorbike on the way to your school. In the middle of your travel, the gas was empty. Luckily there is a gas station nearby. Your father asked you to buy 2 liters of 100 worth of money per 2 liters "premium" gasoline advertised with r=13. But you choose to buy a 93 worth of money per 2 Liters ordinary fuel with r=8. (a) how much decrease in the ideal efficiency results from this decrease in the compression ratio? Use y=1.40. (b) Is it greater than the difference in price?

B) An engine with an indicated thermal efficiency of 50% and mechanical efficiency of 45% consumes 15kg/h of a fuel at a fixed speed. The brake mean effective pressure is 6.5 bar and the mean piston speed is 13m/s. Assuming it is a four cylinder four- stroke square engine, determine the crank radius and the speed in rpm. Take the heating value of the fuel =42MJ/kg and combustion efficiency 100%.

please dinot copy paste from other web i need urgent A petrol engine produces 250 kW while using 1.014 kg of fuel per minute. The fuel has a lower heating value of 45000 kJ/kg, and the engine has bore of 100 mm and the stroke-to-bore ratio of 1.2. The clearance volume of the cylinder is 1.178×105 mm3. The friction power is found to be 10% of the power that engine produces. Sketch (your own) the simple neat and clean block diagram of the engine, clearly indicating the control volume and control surface, with all the given data displayed on it. For air take the value of g = 1.4. Determine the following: The brake thermal efficiency (hb, th ). The indicated thermal efficiency (hind,th ). The mechanical efficiency (hmech ). The brake engine efficiency (hb ). The indicated engine efficiency (hind ). (Hint: Engine efficiency is a function of how the ideal work or power is calculated. Frequently, the air-standard cycle is used for calculating the theoretical work.) Use standard symbols…

As a mechanical engineer, you were asked by your supervisor to monitor the operation of 4-stroke engine; as a result you got the following readings: > Imep = 780 kN/ m2 > Engine speed = 800 rpm > Brake Power 30 kW %3D %3D > nm = 85 % > B/S 0.7 You noticed also, that the inlet valve opens 10° before TDC and closes40° after BDC and it takes 0.0035 second after ignition for the charge to gain maximum pressure. Depending on the above readings, find the following engine parameters: a. The crank angle when the spark occursfor the maximum pressure to be at TDC b. The time period in second of inlet valve opening during one cycle c. The diameter of the engine d. The average piston speed 1 Upload file
