An engine developes a brake power of 20.5kW and consumes 6.0litres of petrol during testing for 45minutes. Assuming the specific density and the calorific value of petrol used were 0.78 and 46MJ/kg respectively; determine the brake thermal efficiency and specific brake fuel consumption. Note: 1litre = 1 kg.

At steady state, air at 200 kpa, 325 k, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. the inlet cross-sectional area is 6 cm2. at the duct exit, the pressure of the air is 100 kpa and the velocity is 250 m/s. neglecting potential energy effects and modeling air as an 1.008 kj/kg k, determine ideal gas with constant cp = (a) the velocity of the air at the inlet, in m/s. (b) the temperature of the air at the exit, in k. (c) the exit cross-sectional area, in cm2
