A four-stroke, 12-cylinder diesel engine has a bore and stroke of 820 mm and 2020 mm, respectively, per cylinder. The brake mean effective pressure of each cylinder is 1.2 MPa and the engine rotates at 145 rpm. The brake thermal efficiency of the engine is 32%, the mechanical efficiency is 72% and the net calorific value of the diesel is 40.75 MJ/kg. 1.calculate the brake power of the engine (MW) ? Answer to 3 decimal places. 2. calculate the indicated power of the engine (MW) ? answer to 2 decimal places. 3. calculate the energy supplied by the fuel (MW)? Answer to 0 decimal place
