An incomplete expansion engine is supplied with steam at 1.95 Mpa and 400C. Release occurs at 0.14 Mpa and exhaust at 50C. Test of the engine showed a brake steam rate of 12.2 kg/kwh and a mechanical efficiency of 82.5%. (a) Find the indicated engine efficiency (b) the brake mep (c) the ideal thermal efficiency of an incomplete expansion cycle operating under the same condition.
