Question

A steam engine develops 45 BHP with dry saturated steam at 1.03425 MPa and exhaust at
0.12411 MPa. Steam consumption is 750 kg/hr. Calculate the thermal efficiency of
equivalent Rankine Engine, in percent.

Use:

@ 1.03425 MPa: hg = 2779.4 kJ/kg; sg = 6.5748 kJ/kg – K

Use these values when necessary: Specific Heat Ratio (k) O2 - 1.395 CO2 - 1.288 Cpwater - 4.187 kJ/kg - K; Cpair - 1 kJ/kg - K; Cpateam - 2 kJ/kg - K H> - 1.4 He - 1.667 NHа - 1.304 N2 - 1.399 Hg - 1.666 CH, - 1.321 1 kg °C to K - (use + 273.15) 1 bar = 100 kPa 1 BTU = 1.055 kJ = 778 ft - lb 1 HP = 2.205 lb 0.746 kW = 2545 BTU/hr @ 1.03425 MPa: @ 2.5 MPa: @ 7MPA and 550 deg C: hg = 2779.4 kJ/kg; S, = 6.5748 kJ/kg - K 2803.1 kJ/kg; Sg %3D ha 6.2575 kJ/ kg - K %3D h, = 3530.9 kJ/kg; si = 6.9486 kJ/kg - K
