The tip speed ratio of a turbine (Figure 5) is the ratio R = T/W, where T is the speed
Chapter 3, Problem 52(choose chapter or problem)
The tip speed ratio of a turbine (Figure 5) is the ratio R = T/W, where T is the speed of the tip of a blade and W is the speed of the wind. (Engineers have found empirically that a turbine with n blades extracts maximum power from the wind when R = 2/n.) Calculate dR/dt (t in minutes) if W = 35 km/h and W decreases at a rate of 4 km/h per minute, and the tip speed has constant value T = 150 km/h.
