# What is a water turbine? (What is Water Turbine in hindi)

Hello friends, in this article we will know what is a water turbine? And what are the types of water turbines? And what are the characteristics of water turbine? You will know many facts related to this.

## Water Turbine

water pressure or kinetic of water energy The machine that converts energy into mechanical energy is called a water turbine.

## Classification of turbine

1. Impulse turbine or Pelton Wheel
2. Reaction turbine or Francis and Kaplan turbine

In an impulse turbine, a jet of water falls on the blades and the turbine starts moving with the impulse of water.

In a reaction turbine, the blades move due to the pressure difference on either side. Or it can be of any type Radial or Axial.

## Characteristics of turbine

The main characteristic of a turbine is its specific speed, its definition is as follows –

The speed of a geometrically similar turbine, which delivers unit power at the unit head, is called specific speed. Specific Speed ​​in British Unit (N)s) has the following formula –

Ns = (N√HP)/H5/4 rpm

Here, N = Rotational speed in rpm
HP = Horse power of Wheel
H = Head of Water in meter

If the power is displayed in kilowatts, then the above formula will be as follows –

Ns = (1.165 N√kW)/H5/4 rpm
