In an ideal Diesel cycle, the pressure and temperature are 1.03 bar and 27 ◦C, respectively. The maximum pressure in the cycle is 47 bar and the heat supplied during the cycle is 545 kJ/kg. Determine (i) the compression ratio (ii) the temperature at the end of compression (iii) the temperature at the end of constant pressure combustion and (iv) the air-standard efficiency. Assume γ= 1.4 and cp = 1.004 kJ/kg K for air? Please solve this problem?
Mala ek problem ahe heat power madhe 1). An engine working on Otto cycle has diameter 150 mm and length 225 chief clearance volume is 1.25 into 10^3 m^3find air standard efficiency
Q1:- Find out the speed at which a four-cylinder engine using natural gas can develop a brake power of 50 kW working under following condition air gas ratio 9:1, calorific value of the fuel = 34 MJ/metre cube, compression ratio 9:1, volumetric efficiency = 70%, indicated thermal efficiency = 35% and the mechanical efficiency = 80% and the total volume of the engine is 2 litres. Must send me the solution bro with explanation
Q2:- Fuel supplied to an SI engine has calorific value 42000 kJ/kg. The pressure in the cylinder at 30% and 70% of the compression stroke are 1.3 bar and 2.6 bar respectively. Assuming that the compression follows the low PV^1.3 = constant. Find the compression ratio. If the relative efficiency of the engine compared with the air standard efficiency is 50%. Calculate the fuel consumption in Kg/kW h.
Best best best ❤️❤️❤️❤️
Thank you
Your video is very helpful for me❤️❤️❤️❤️
Most welcome 😊
Amazing contend well done carry on 👌

5:35 how we can solved it w/o calculator
sir can you explain V Ganesan solved question Q3.3

I didnt see the pressure at the end of expansion stroke(p4=?)
Thnks bro
0 degree Celsius is equal to 273.15 K or 273K
👍🏻👌
Hi sir
eficiency of diesel is incorrct
Ya I have mentioned in my next video
bro can you explain V Ganesan solved question Q3.3
Are you asking from video question or question from other book
