Brake Thermal efficiency of Diesel Engine - GATE ME '99

A large diesel engine runs on a 4-stroke cycle at 2000 rpm. The engine has a displacement of 25 liters and a brake mean effective pressure of 0.6 MN/m2. It consumes 0.018 kg/s of fuel (calorific value = 42000 kJ/kg). Determine the brake power and brake thermal efficiency.
