Question

Discuss the advantages of dimensional and model analysis.

Answer 1

To make everything clear I have written the answers that I have learnt very precisely in my handwriting and for more convinience ..I have typed them too...?

Here are the typed answers

The followings are the advantages of the dimensional and model analysis:
1. The performance of the hydraulic structure or hydraulic machine can be easily predicted, in advance,
from its model.
2. With the help of dimensional analysis, a relationship between the variables influencing a flow probem
in terms of dimensionless parameters is obtained. This relationship helps in conducting tests on the
model.
3. The merits of alternative designs can be predicted with the help of model testing. The most economical
and safe design may be, finally, adopted.
4. The tests performed on the models can be utilized for obtaining, in advance, useful information about
the performance of the prototypes only if a complete similarity exists between the model and the
prototype
