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
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?
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 👌

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