A 302 in displacement, V8, four-stroke cycle SI engine mounted on a hydraulic dynamometer has an output of 72hp and 4050 RPM. Water absorbs the energy output of the engine as it flows through the dynamometer at a rate of 30 gallons per minute. The dynamometer has an efficiency of 93% and the water enters at a temperature of 46*F. Calculate the exit temperature of the water in degrees Fahrenheit
