A wind turbine is 12 m in diameter. The wind blowing through it is blowing at 6.1 m/s. The efficiency of the turbine in 1.5%. The density of the air is 1.225 kg/m3 . What is the power output of the turbine

An open feedwater heater operates at steady state with liquid entering at inlet 1 with t? = 40°c and pl = 1 .2 mpa. water vapor att2-200°c and p2 = 1.2 mpa enters at inlet 2. saturated liquid water exits with a pressure of pa 1.2 mpa. neglect heat transfer with the surroundings and all kinetic and potential energy effects, determine the mass flow rate of steam at inlet 2 if the mass flow rate of liquid water at inlet 1 is given as 2 kg/s.
