QUESTION 3 A single-cylinder, 4-stroke, 3-liter gasoline engine operates at 646 rpm and a compression ratio of 9. The pressure and temperature at the intake are 101.0 kPa and 32 °C respectively. The fuel used has a heating value of 42,500 kJ/kg, the air-fuel ratio is 14, and 77.2 % mechanical efficiency. The length of the indicator card is 55.1 mm with an area of 503.7 mm² and the spring scale is 0.85 bar/mm, considering a volumetric efficiency of 93.6% and a 24% excess air. Determine Brake Heat Rate in kJ/kW-hr. Note: Use two (2) decimal places in your solution and answer.
The attached answer was provided for the attached question. The equation uses the given temperature in celcius and the answer is also given in celcius. The temperature was used in the equation without converting from F and the answer was supposed to be in F. I am worried that even if I converted the answer to celcius that it would be correct because temperature was used in the equation using the incorrect unit.
