Question

A horizontal shaft, propeller type wind-turbine is located in area having speed of wind $10\text{ m/s}$ at $1\text{ atm}$ and $15^{\circ}$ 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 $120\text{ m}$ dia.
