Hydraulic turbine -
The main classification depends upon the type of action of the water on the turbine. These are :
(i) Impulse Turbine
(ii) Reaction Turbine.
(i) Impulse turbine:-

In the case of an impulse turbine, all the potential energy is converted to kinetic energy in the nozzles. The impulse provided by the jets is used to turn the turbine wheel.
This type is found suitable when the available potential energy is high and the flow available is comparatively low.
The relative velocity over the moving blades either remains constant or slightly decreases so the correct answer is option 1

(ii) Reaction Turbine:-

In reaction turbines, the available potential energy is progressively converted in the turbine's rotors and the reaction of the accelerating water causes the turning of the wheel.
The relative velocity over the moving blades increases.
These are again divided into (a) radial flow, (b) mixed flow, and (c) axial flow machines

Similar Civil Engineering (CE) Doubts

A water turbine is stated to have 50 percent degree of reaction. What is the physical meaning of this statement? Classify the Pelton, Francis and Kaplan runners according to the ranges of degree of reaction. Does the specific speed increase or decrease with an increase in the degree of reaction of a hydraulic turbine?The velocity and pressure head at the entrance to the volute casing of a Francis turbine are 10 m/s and 240 m, and the elevation above tail race is 5 m. The shaft is vertical and the machine discharges 15 m3⁄s when turning 450 revolutions per minute. The mean diameter for the runner blades is 2 m and the width at inlet is 28 cm. If the discharge is to be axial, calculate:(i) the specific speed(ii) the degree of reactionAssume values for the hydraulic and overall efficiencies are 94% and 92% respectively.

Consider the following statements with regard to hydraulic turbines:1. Kaplan turbines are most efficient at part load operations.2. If n is the number of jets in a Pelton turbine, then the specific speed is proportional to n2.3. The flow ratio of Francis turbines are in the range of 0.1-0.3.Which of the above statements is/are correct?

View answer

The correct sequence of the given hydraulic turbines in decreasing order of their specific speeds is

View answer

Mainly hydraulic turbines are used to drive the electrical alternators which require maintaining the peripheral speed constant even at part load conditions to avoid the change in frequency of electric power. The governing of the hydraulic turbine is done by
