A gasoline turbine works with a stress ratio of 6:1. The temperature and pace of gases on the inlet to the turbine are 900 k and 350 m/s, respectively. The isentropic expansion performance is said to be eighty five%. The speed of gases at the outlet is 50 m/s. The specific warmness of gases, cp, over the running range can be taken as 1.004 kJ/kg k and F 1.4. decide the energy output of the turbine for the unit mass drift charge of gases
