Hydrogen enters the turbine of an ericsson cycle at 1160 k, 5 bar with a mass flow rate of 1 kg/s. at the inlet to the compressor the condition is 300 k and 1.5 bar. assuming the ideal gas model and ignoring kinetic and potential energy effects, determine: (a) the net power developed, in kw. (b) the percent thermal efficiency. (c) the back work ratio.
