A wind turbine is designed to produce the power of 5 kW. What is the percentage of mechanical and electrical conversion if the value of C, is 0.45, Wind speed is 5 m/s length of the blade is 15 m density of air is 1.12 kg/m?.
1. Do a project research based on this topic. Gas turbines are used for many purposes from aeroplane engines to industrial electric power generating sets. They are at the heart of most jet engines but also for propeller driven engines. Hence, do a mechanical report on operation for gas turbine plant and justify its operation.
A crate of mass m = rough ramp at a constant speed v by a motor with a power input of Pm = 2 kW. The ramp is angled at 0 = 40° with respect to the horizontal, and the coefficient of friction between it and the crate is u = 0,5. Find the crate's speed v up the ramp if the motor is 60% efficient.
