The average wind velocity in a particular area is found to be 5.5m/s. It is proposed to install a wind driven turbine with a blade radius of 1.8m. The

proposed design has an interference factor of 0.21 and a torque coefficient of 0.8.

Determine:

a) The expected power output of the turbine.

b) Thrust on the turbine.

c) Torque on the turbine.

d) Rotational speed.

Note: Assuming the air density is 1.2 kg/m3​

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.

Which of the following is an easy way to remember the modified “x” tire rotation? a. nondrive wheels straight, cross the drive wheels b. drive wheels straight, cross the nondrive wheels c. drive wheels crossed, nondrive wheels straight d. drive wheels crossed, nondrive wheels crossed

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