Air enters a gas turbine at PI = 1 10 0 kPa and [! = 860 k and leaves the turbine at P 2 - 100 kPa andI2 = 450 K . Air enters the turbine through a pipe with an internal cross- section of 0. 3 m- and anaverage velocity of 10 mi's , and exhausts through a larger pipe with an internal cross- section of \mP 1 = 1 . 1 MP`T 1 = 850 KV 1 = 20 m/'sHE ? , VE = ?InletWV = ?Turbine*Outlet*P 2 = 100 KP`I 2 = 450 K12 = ?, V 2 = "?V 2 = ?FigureAir turbine running at steady state*You can assume thatChange of Potential energy is negligible .Change of Kinetic energy is not negligible .Turbine is well insulated and there is no heat transfer ..Air is an ideal gas .The turbine operates at steady state .Please answer the following questions :"a )Determine the inlet specific enthalpy ( he ) and inlet specific volume ( 1 1 ) .b )Determine the mass flow rate of air through the turbine .*C )Determine the specific enthalpy at outlet ( 12 ) and specific volume at outlet ( 1 2 )d )Determine the average velocity of air at outlet , V/ 2 .e )Determine the power is produced by the turbine in KW .
