Pick the correct order of various turbines with respect to specific speed.
A water turbine delivering 10 MW power is to be tested with the help of a geometrically similar 1 : 10 model which runs at the same speed and efficiency. The power developed by the model will be:
In general sense, water turbines may be put in the following decreasing order of specific speeds as
Consider the following statements in connection with hydraulic turbines:1. The Kaplan turbine is a radial flow turbine in which the guide vane angles as well as the runner vane angles are adjustable.2. Francis and Kaplan turbines are provided with draft tubes which carry water from exit of runner to tail water to increase the gross head across the turbine.3. The parts of turbines susceptible to cavitation are the guide vanes and runner vanes – drastically reducing the turbine efficiency.4.
