1. Consider the Hoover Dam hydro-electric plant located in Arizona and Nevada. If the average lake level is 160 m above the turbine outlet, determine the minimum mass flow rate of water through the 17 turbines if the total power produced from all four turbines is 2080 MW. What is the mass flow rate if the turbines are 88% efficient.?
2. What is the possible power (kW) production from a 32 m radius wind turbine if the average wind speed is 12 m/s? Assume an ambient air density of 1.20 kg/m3.
