A 150 hp diesel engine for running an emergency generator in a building ha sa compression ratio of 19 with a cutoff ratio of 1.8. It rejects its heat by way of cooling water that goes to a radiator. The cooling water enters the engine at 85 deg F and leaves at 110 deg F. What flow rate of cooling water is required in gallons per minute (gpm)? What size sch 40 steel pipe (inches) would you use to route this cooling wawter to and from the engine to the radiator? You can assume an ideal Diesel cycle.
