A torque of 200 ft-lb is developed by a diesel engine when running at 1200 rpm and using 20lbs of fuel per hour. The heating value of the fuel is 19,000 BTU/lb. The engine is of 4-stroke cycle and has 4 cylinders. The bore equals to stroke. The engine takes in 25lbs of air per lb of fuel. The volumetric efficiency is 80%, T=60°C. Calculate the brake thermal efficiency and the bore in inches. Assume that it is operated at standard condition.
