Reaction turbines are acted on by water, which changes pressure as it moves through the turbine and gives up its energy. They must be encased to contain the water pressure (or suction), or they must be fully submerged in the water flow.
Newton's third law describes the transfer of energy for reaction turbines.
Most water turbines in use are reaction turbines and are used in low (<30m/98 ft) and medium (30-300m/98984 ft) head applications. In reaction turbine pressure drop occurs in both fixed and moving blades.
Impulse turbines change the velocity of a water jet. The jet pushes on the turbine's curved blades which changes the direction of the flow. The resulting change in momentum (impulse) causes a force on the turbine blades. Since the turbine is spinning, the force acts through a distance (work) and the diverted water flow is left with diminished energy.
Prior to hitting the turbine blades, the water's pressure (potential energy) is converted to kinetic energy by a nozzle and focused on the turbine. No pressure change occurs at the turbine blades, and the turbine doesn't require a housing for operation.
Newton's second law describes the transfer of energy for impulse turbines.
Impulse turbines are often used in very high (>300m/984 ft) head applications.

Small hydro power plants
Before you can begin planning your systems or estimating how much power you'll produce, you'll need to make four essential measurements:
1. Head (the vertical distance between your intake and turbine)
2. Flow (how much water comes down the stream)
3. Pipeline (Penstock) length
4. Transmission Line length
In this section, we'll discuss how to make these measurements and how they affect the design and efficiency of your hydro system.
