For a gas turbine operating at a pressure ratio of 8.7 the maximum temperature ratio to be maintained

such that the turbine just supports the compressor, which is given by
 = 3.0. If the compressor inlet total temperature and the turbine efficiency are respectively 300 K and 0.75, find the following:

(i) the compressor efficiency

(ii) the temperature ratio at which the compressor work is 80% of the power produced by turbine. Also find the corresponding heat addition and Network output per unit mass flow in the gas turbine. Take
  = 1.005 kJ/kg K and
   = 1.147 kJ/kg K.
