Test: Fluid Machines - 2 - Question 2

The specific speed of a turbine is defined as the speed of a Unit of such a size that it

Test: Fluid Machines - 2 - Question 3

A high efficiency pump is required for low discharge, high head and low maintenance cost. Delivery of water need not be continuous. The pump need not run at high speed. Which one of the following is the correct choice?

Test: Fluid Machines - 2 - Question 4

A reaction type turbine discharges 10 cumecs under a head of 8 m and with an overall efficiency of 85 percent, The power developed is

Detailed Solution for Test: Fluid Machines - 2 - Question 4

Power developed

Test: Fluid Machines - 2 - Question 5

Which one of the following statements is correct?

Test: Fluid Machines - 2 - Question 6

An impulse turbine

Test: Fluid Machines - 2 - Question 7

In the selection of turbine by specific speed or head, which one of the following statements is not correct?

Detailed Solution for Test: Fluid Machines - 2 - Question 7

 

  1. For specific speed 10-35, Kaplan turbines

This statement is incorrect because Kaplan turbines are designed for much higher specific speeds. The correct range for Kaplan turbines is generally from 300 to 1000 (in metric units), making this option inaccurate.

Test: Fluid Machines - 2 - Question 8

For 25 m or less available head which turbine will be suitable:

Detailed Solution for Test: Fluid Machines - 2 - Question 8

For low head of 1.5 to 20 metres Kaplan turbines and francis turbines are used. 
For high head (> 25m) pelton wheel turbine is used. 

Test: Fluid Machines - 2 - Question 9

The hydraulic efficiency of an impulse turbine is maximum when velocity of wheel is (Where: V = jet velocity)
