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

Fluids at rest possess no flow energy. a)- true b)- false

Slip occurs via two partial dislocations because of (a) the shorter path of the partial dislocation lines; (b) the lower energy state through partial dislocations; (c) the charge balance.

Asteam is contained in a rigid tank with a volume of 1 m3. initially, the pressure and temperature are 7 bar and 500 oc, respectively. the temperature drops due to cooling process. determine: (1) the temperature at which condensation begins in °c, (2) the fraction of the total mass that has condensed when the pressure decreased to 0.5 bar. (3) the volume in m3 occupied by saturated liquid at the final state?
