Question

A horizontal shaft, propeller type wind-turbine is located in area having speed of wind 10 m/s at 1 atm and $15^{\circ}\text{ C}$. Calculate the following:

(i) Air density $\rho$

(ii) Total power density in wind stream, $\text{W/m}^2$.

(iii) Maximum possible obtainable power density, $\text{W/m}^2$.

(iv) Actual obtainable power density, $\text{W/m}^2$.

(v) Total power from a wind-turbine of 120 m dia.
