Does electrical power equal mechanical power?

For an electrically driven motor, the output power is mechanical while the input power is electrical, so the efficiency equation becomes efficiency = mechanical power/electrical input power.

How is electrical power related to mechanical power?

So What is the Difference? The mechanical power is measured by the rate at which work is done. On the other hand, electrical power is measured by the rate at which electrical energy is transformed.

What is the power of a turbine?

To calculate electrical power or turbine power, you have to know the hydraulic power, which depends on the flow and how far the water falls. So, the hydraulic output power is equal to gravity times flow (in litres per second) times the pressure or height difference (in metres of water column).

How many RPM does a generator need?

Typically, a United States portable generator runs at 3600 RPM, with 2 poles, for a design frequency of 60Hz. Larger portable generators run at 1800 RPM with 4 poles here.

How is electrical power calculated?

Electrical power is the product of voltage and current. P=VXI. P = V X I .

What is the relation of power to work energy force and velocity?

These two definitions are equivalent since one unit of energy must be used to do one unit of work. Often it is convenient to calculate the average power. In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv.

How is turbine power calculated?

Power output is calculated as follows: power = [(air density) times (swept area of blades) times (wind speed cubed)] divided by 2. The area is in meters squared, air density is in kilograms per meters cubed and wind speed is in meters per second.

How does the power in the turbine change with speed?

Variation of power turbine power output with power turbine speed for a series of gas generator speeds. For a given gas generator speed, there is a region where the power output increases with power turbine speed. This increase is primarily due to an increase in power turbine efficiency.
