Question

Match List I and with List II and select the correct answer using the code given below the lists:

$\begin{array}{cc}\text{List-I}& \text{List-II}\\ \text{P.Pelton Turbine}& \text{1.Draft tube}\\ \text{Q.Francis Turbine}& \text{2.Manometric Head}\\ \text{R.Kalpan Turbine}& \text{3.Mixed Flow}\\ \text{S.Centrifugal pump}& \text{4.No cavitation}\end{array}$

Codes:

• A. P - 4, Q - 3, R - 1, S - 2
• B. P - 4, Q - 3, R - 2, S - 1
• C. P - 4, Q - 2, R - 1, S - 3
• D. P - 2, Q - 1, R - 4, S - 3

Answer 1

The correct option is A P - 4, Q - 3, R - 1, S - 2

• In Pelton turbine runner is exposed to atmospheric pressure. Hence, chances of cavitation are minimum.
• Modern Francis turbine has radial entry and axial exit of water. Hence, it is called mixed flow turbine.
• Draft tube is used in reaction turbines i.e., both Franices and Kalpan turbines.
• Manometric head represents the output of centrifugal pump.
