A reciprocating engine may be considered a steady fl ow device if there is enough “receiver” capacity on either side of it to smooth out variations in pipeline conditions caused by the intermittent action of the engine. The “indicated work” of an engine is the net work done on the piston. A small reciprocating engine is supplied with steam at 6.5 MPa and 420°C. The steam exhausts at 2 MPa and 280°C. If the heat loss from the engine cylinder to the atmosphere is 1.2 kW and the steam fl ow is 900 kg/h, fi nd the indicated power of the engine.
