A Locomotive starts from rest and pulls a train, weighing 20 X 106 N down a 1per cent grade. The train resistance is 5 N/kN. If the draw-bar pull is constant and equal to 50 kN find the speed of the train after it has moved 1500 m. Find the final horse power developed by the engine.​

An engine runs on the ideal diesel cycle. the cycle has a compression ratio of 20 and a cutoff ratio of 2. the highest temperature in the cycle is 1200 k. if the heat into the system is 300 kj/kg of working fluid and using variable specific heats determine the work produced per mass of working fluid
