A five-cylinder, 3.5-liter SI engine operates on a four-stroke cycle at 2500 RPM. At this condition, the mechanical efficiency of the engine is 62% and 1000 J of indicated work are produced each cycle in each cylinder.

Calculate:

(a) Indicated mean effective pressure. [kPa]

(b) Brake mean effective pressure. [kPa]

(c) Friction mean effective pressure. [kPa]

(d) Brake power in kW and hp.

(e) Torque. [N-m]
