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​

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

The drive force for diffusion is 7 fick's first law can be used to solve the non-steady state diffusion. a)-true b)-false

An ideal otto cycle with air as the working fluid has a compression ratio of 8. the minimum and maximum temperatures in the cycle are 300 k and 1340 k. use constant specific heats at room temperature to determine (a) the amount of heat transferred to the air during the heat- addition kj/kg, (b) the thermal efficiency, and (c) the thermal efficiency of a carnot cycle ope limits. process, in rating between the same temperature
