Test: Dimensional & Model Analysis, Centrifugal Pump - 1 - Mechanical Engineering MCQ

Match List-I (Industrial needs) with List-II (Type of pump) and select the correct answer using the codes given below the Lists:  

The correct sequence of the centrifugal pump components through which the fluid flows is:  

What will be the shape of the velocity triangle at the exit of a radial bladed centrifugal impeller, taking into account slip? 

The power absorbed by a hydraulic pump is directly proportional towhich one of the following? 
(Where N is the rotational speed of the pump)

Consider the following statements pertaining to a centrifugal pump:
1. The manometric head is the head developed by the pump. 
2. The suction pipe has, generally, a larger diameter as compared tothe discharge pipe.
3. The suction pipe is provided with a foot valve and a strainer.
4. The delivery pipe is provided with a foot valve and a strainer.
Of these statements:

A pump running at 1000 RPM consumes 1 kW and generates head of 10m of water. When it is operated at 2000 RPM, its power consumptionand head generated would be:  

A centrifugal pump gives maximum efficiency when its blades are: 

The vanes of a centrifugal pump are generally 

Assertion (A): Multi-stage centrifugal pumps are only of the radial flowtype.  
Reason (R): In a multi-stage centrifugal pump, two or more impellersare keyed to a single shaft and enclosed in the same casing, the radialinlet to successive impellers being made through guide vanes.

If the number of fundamental dimensions equals 'm', then the repeating variables shall be equal to: 

The square root of the ratio of inertia force to gravity force is called 

In flow through a pipe, the transition from laminar to turbulent flowdoes not depend on  

Given power 'P' of a pump, the head 'H' and the discharge 'Q' and the specific weight 'w' of the liquid, dimensional analysis would lead to the result that 'P' is proportional to: 

If the number of fundamental dimensions equals 'm', then the repeating variables shall be equal to:  

Consider the following statements:  
1. Dimensional analysis is used to determine the number of variables involved in a certain phenomenon
2. The group of repeating variables in dimensional analysis should include all the fundamental units.
3. Buckingham's π theorem stipulates the number of dimensionless groups for a given phenomenon.
4. The coefficient in Chezy's equation has no dimension.
Which of these are correct?

Which one of the dimensionless numbers identifies the compressibility effect of a fluid? 

It is observed in a flow problem that total pressure, inertia and gravityforces are important. Then, similarly requires that
