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

Explanation:

From the question we are told that:

Output Power

Density

Wind speed

Efficiency

Let Betz Limit

Generally the equation for Turbine Efficiency is mathematically given by

Where

P'=input power

Therefore the blade diameter for a two-blade propeller type rotor is

answer:

science is the study of the nature and behavior of natural things and the knowledge that we obtain about them. a science is a particular branch of science such as physics, chemistry, or biology. physics is the best example of a science which has developed strong, abstract theories.

pseudoscience is a collection of beliefs or practices mistakenly regarded as being based on scientific method.

the warning light flashes for a second or two when the engine starts. if it stays on, there's must be something wrong with the coolant. you should never dare to continue driving when the light is on. pull over as soon as possible and shut the engine off.

hope this is what you're talking about
