The straight line showing the variation in WC with qp is obtained by noting from eqn. 8) that WC varies linearly with qp and would have a value equal to cp(Tb—Ta) when the compressor outlet temperature Tv equalled Tb\ from eqn. c(0-l). 15) Thus WC cp(Tb-Ta) is equal to unity when qp = β. The straight line showing the variation of the heat input QB with qp is obtained by noting that QB also varies linearly with qp9 since it is given by QB = cJTi-Tr) = cp(Tb-Ta)- WC.

A petrol engine is fitted with a turbo-supercharger, which comprises a centrifugal compressor driven by an exhaust gas-turbine. The gravimetric ratio of air to fuel supplied to the engine is 12, the fuel being mixed with the air between the compressor and the engine. 5 bar. 3 bar and a temperature of 510 °C and leave the turbine at a pressure of 1 bar. The isentropic efficiencies of the turbine and compressor are each 80 %. Assuming that the thermal properties of the exhaust gases are the same as for air, calculate: (a) the temperature of the air leaving the compressor; (b) the temperature of the gases leaving the turbine; (c) the power loss in the turbo-supercharger, due to external friction, expressed as a percentage of the power generated in the turbine.

7) To(SRo—SP() is the heat transferred to the environment in the ideal, reversible work-prcducing process. This is positive for some reactions and negative for others, and is usually fairly small compared with the calorific value. 1. Since the ideal work output is —AGQ, the greatest possible value of the arbitrary overall efficiency η0 is as given in the last column of the table. The resulting anomalous situation of the ideal efficiency being in one case slightly in excess of 100 % does not worry the engineer unduly, since, for reasons which will be seen shortly, turbine a n d reciprocating plant have actual values of η0 always well below 100 %.
