Consider a wind turbine subjected to 30 km/hr steady winds. if the turbine produces 480 kw of power and the velocity downstream of the wind turbine is 25 km/hr, determine the turbine efficiency, turbine diameter, and the horizontal force exerted by the wind on the supporting mast of the turbine. take density of air to be 1.25 kg/m^3

When at a point two solid phase changes to one solid phase on cooling then it is known as a) eutectoid point b) eutectic point c) peritectic point d) peritectoid point

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false
