Where is Kaplan turbine used?
Kaplan turbines are widely used throughout the world for electrical power production. They cover the lowest head hydro sites and are especially suited for high flow conditions
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan,[1] who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level.
The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from 10 to 70 metres (33 to 230 ft) and the output ranges from 5 to 200 MW. Runner diameters are between 2 and 11 metres (6 ft 7 in and 36 ft 1 in). Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm (Albeni Falls Dam) to 450 rpm.[2]
Kaplan turbines are now widely used throughout the world in high-flow, low-head power production

What is the difference between Kaplan and Francis turbine?
General differences between Francis and Kaplan turbines
Kaplan turbine is more compact in cross-section and has lower rotational speed to that of Francis turbine. ... The Francis Turbines specific speed is medium (60-300 rpm) and Kaplan Turbines specific speed is high (300-1000 rpm).
Which turbine is most efficient?
Impulse turbines are most efficient for use in cases where the flow is low and the inlet pressure is high. Reaction turbines develop torque by reacting to the gas or fluid's pressure or mass.
Which turbine has highest discharge?
Explanation: Based on heads and discharges, turbines are classified into Pelton, Francis or Kaplan. Pelton has high head and low discharge.
