Question

Problem 8 A wind turbine with a 60m diameter swept area is operating at an elevation of 600m, spinning at a TSR of 10, with ß-10°, at a Cp of 27.5%, in horizontal winds of 17 m/s, and generating 2 Mw of power. What is the air density?

Answer 1

We have power output of wind turbine is given by P

=$P=\frac{\rho *C_{p}*U^{3}*\pi *d^{2}}{8}$   

on substitutng the given values we will get

ρ*0.275 * 173 * π * 602 2 10 1.0470kg/m
