For a 50 m diameter turbine in a 30 mph wind, determine
(a) The mass flow rate of air (in kg/s) intercepted by the turbine.
(b) The specific kinetic energy (ke) of the flow (in kJ/kg),
(c) The rate of transport of kinetic energy kW.
(d) The maximum possible shaft power. Assume density of air as 1.1 kg/m3 and use Betz's law.
(e) What-if Scenario: What will be the maximum shaft power if the wind velocity drops to 15 m/s?
