Q4. Data is given for a 4 stroke internal combustion Diesel engine.

Understand and prepare the heat balance sheet on the kJ/min basis

1. Speed of the Engine = 450 RPM

2. Oil consumption = 3.5 kg/hr

3. Water flow = 270 kg/hr

4. Rise in cooling water temperature = 360 C

5. Air fuel Ratio = 25

6. Exhaust gas temperature = 700k

7. Room Temperature = 300k

8. C.V of Fuel = 45,000 kJ/kg

9. Brake power = 12 kW

10. Specific heat of the Exhaust gas = 1.005 kJ/kg K
