A 302-in³. displacement, V8, four-stroke cycle SI engine mounted on a hydraulic dynamometer has an output of 72 hp at 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:

(a) Exit temperature of the water. [°F]

(b) Torque output of the engine at this condition. [lbf-ft]

(c) What is the bmep at this condition? [psia]
