An airfoil profile to be used on a wind turbine blade is tested in a wind tunnel. The prototype (full-scale) airfoil section has a chord length of 2m and moves at 50 m/s relative to the wind, the wind tunnel model has a chord length of 0.4m. The temperature for the model test is the same as for prototype operation. (a) What criterion should be used to obtain dynamic similarity in the experiment? (Write out the criterion in an equation.)...

Green Batteries Pty Ltd is considering the purchase of a wind turbine generator in order to generate electricity and to reduce the electricity costs for their offices, which are located in Toowoomba. Currently the business uses 40,000 kilowatt hours (kWh) per quarter (3 months) at an average cost of $0.40 per kWh, supplied by the local coal fired power station. The current required rate of return used to evaluate projects is 6%, with a required payback period of 4 years....

A 3-blade wind turbine with a diameter of 16 m spins at 35 rpm at a 5000 m elevation where the average wind speed is 30 km/hr. The atmospheric pressure and temperature at that location are 98 kPa and -10 oC, respectively. There is a rotating wake behind the turbine. Neglecting the frictional drag, calculate the maximum power coefficient and maximum power.
