Explain the working principle of a water turbine.

1.	Explain the working principle of a water turbine.
Answer» Turbines are essentially propellers in reverse, both of which work in direct accordance to Isaac Newton’s third law – namely, for every action there has to be an equal and opposite reaction. In propellers, that means energy is put into a spindle of asymmetrical blades that puts pressure on the air or water, which pushes back to propel the vehicle. Turbines are usually fixed in place, so when a fluid flows through it there is a drop in pressure at the back edge of each blade that causes the turbine to turn. The principle is the same for air or water and the faster the medium is moving, the greater the pressure drop, and the faster the turbine spins.
