Show from the following data taken for the automobile test performed on a 4-cylinder gasoline engine calculate the Brake Thermal Efficiency: Fuel intake = 9.78 lb/hour Brake output = 36.5 HP Specific gravity of gasoline at 60F = 0.738 Room temperature = 78.5 F Throttle Setting = 9/16 full throttle High heating value (HHV) = 25,960 BTU/lb Conversion factor 1HP = 2,545 BTU/hour Brake Thermal Efficiency in percent 100 3,600 100 = = Q HHV P INPUT OUTPUT f f t MUST show all steps. MUST show units in each step. 1 horsepower [international] = 0.746 kilowatt 1 kilogram = 2.204 lbs 1 BTU = 1.055 kilo joules Round off ALL answers to three decimals
