Consider the design of a home-built wind turbine using a 350-W automobile dc generator. The goal is to deliver 70kWh in a 30-daymonth.

a. What capacity would be needed for the machine?

b. If the average wind speed is 5 m/s, and Rayleighstatistics apply, what should the rotor diameter be if thecorrelation of (6.65) is used?
c. How fast wouldthe wind have to blow to cause the turbine to put out its full 0.35kW if the machine is 20% efficient at thatpoint?d. If the tip-speed-ratio isassumed to be 4, what gear ratio would be needed to match the rotorspeed to the generator if the generator needs to turn at 1000 rpmto deliver its rated 350 W?
