120 (Question: 139383.0 )

The following criteria are required to achieve similitude;

Geometric similarity – The model is the same shape as the application, usually scaled.
Kinematic similarity – Fluid flow of both the model and real application must undergo similar time rates of change motions. (fluid streamlines are similar)
Dynamic similarity – Ratios of all forces acting on corresponding fluid particles and boundary surfaces in the two systems are constant.

Question:

Kinematic similarity between Model and prototype is the similarity of

Options:
A) Shape 
B) Discharge / Motion
C) Stream
D) Forces
Solution:

Ans: (b) If the ratio of velocity and acceleration at the corresponding points in the Model and prototyle are same then there exist kinematic similarity.
