Determining the Efficiency of the Hot-Air Engine as a Heat Engine

The experiment P2.6.2.2 determines the efficiency of the hot-air engine as a heat engine. The mechanical work W exerted on the axle in each cycle can be calculated using the external torque N of a dynamometrical brake which brakes the hot-air engine to a speed f. The amount of heat Q2 given off corresponds to a temperature increase ΔT in the cooling water.
