You are required to design a wind turbine, which can generate 1.2 kW of electrical power. The wind turbine is located at a place with an average wind speed of 17.5 mph. If the system component efficiency is 60% , calculate the blade diameter for a two-blade propeller type rotor.(Density of air

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
