In an axial flow gas turbine the hot gases approach the rotor inlet with an absolute velocity of 600 m/s in a direction 300 from the wheel tangent. The gases leave the rotor axially. If the blade speed is 300 m/s then the theoretical power output per kg/s of gas flow will be approximately
(a) 132 kW (b) 156 kW (c) 172 kW (d) 205 KW
