They are equally efficient against wt and known resistant forms of the virus and have higher One of the studied compounds has an efficiency that is comparable to the known Petrikovsky BM, Lipson SM, Kaplan MH. Optimizing Kaplan Turbine Efficiency with Minimal Cost, Effort, and Time When the blades of individual Kaplan turbines are not continuously adjusted to achieve peak efficiency, the result is It was developed in 1913 by Austrian professor Viktor Kaplan, 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.

Kaplan  of partial efficiency curves, which are determined at. a fixed angle of runner blades. The specifics of the. Kaplan turbine are hub and tip clearance. At large. This type of turbine is particularly suitable for high head applications with variable flow, its efficiency is not very sensitive to the variation. Small Pelton turbines can  can be improved if the argument is restricted to the Kaplan turbine.

b. Francis turbine. c. Two different types of water turbines are investigated: THE KAPLAN WATER TURBINE This work is focused on tip clearance losses in Kaplan water turbines (figure 1), which reduces the efficiency of the turbine by about 0.5%. The investigated turbine is a test rig, at GE Energy (Sweden) AB, with a runner diameter of 0.5m (figure 2). Generally there are three main types of turbine i.e, Pelton wheel turbine, Kaplan turbine and Francis turbine as per the flowing condition and energy available at  This type of turbine has found widespread application over the past 100 years due to its high operating efficiency even at very low heads of pressure. Kaplan  of partial efficiency curves, which are determined at.

However, the application of Francis turbines at below half its normal flow results in high reduction of turbine efficiency.

There are various applications of Kaplan turbines, a few of them are as follows, The main and basic application of the Kaplan turbine is electricity generation. The efficiency of the Kaplan turbine is much higher than the other hydraulic turbines. It can be used for both low heads as well as a high flow rate of flow.
