Similitude

 

The three types of similarities are,

 

1.   Geometric similarity

 

2.   Kinematic similarity

 

3.   Dynamic similarity

 

Scale ratio.

 

Scale ratio is the ratio of linear dimension in the model and prototype which are equal in a geometric similarity. It is denoted by Lr.

Lr = Lp/Lm = bp/bm = Dp/Dm

 

 

Dynamic similarity.

 

It means the similarity of forces at corresponding points in the model and prototype is equal.

 

Types of forces in a moving fluid.

 

The types of forces in a moving fluid are,

 

1.   Inertia force (fi)

 

2.   Viscous force (fv)

 

3.   Gravity force (Fg)

 

4.   Pressure force (Fp)

 

5.   surface tension (Fs)

 

6.   Elastic force (Fe)

 

Dimensionless numbers.

 

Dimensionless numbers are the numbers obtained by dividing inertia force or gravity force or pressure force or elastic force or surface tension. They are called as non-dimensional parameters.

 

Surface tension.

 

Surface tension force is defined as the product of surface tension and length of surface of flowing fluid.

Pressure force.

 

Pressure force is the product of pressure intensity and cross-sectional area of the flowing fluid in case of pipe flow.

 

Elastic force.

 

Elastic force is defined as the product of elastic stress and the area of flowing fluid.

 

Types of dimensionless numbers.

 

The types of dimensionless numbers are:

 

1.   Reynold’s number

 

2.   Froude’s number

 

3.   Euler’s number

 

4.   Weber’s number

 

5.   Mach’s number

 

Reynold’s number.

 

Reynold’s number is defined as the ratio of inertia force of flowing fluid and viscous force of the fluid. It is denoted by (Re)

 

Re = V x d / v = ? V d / ?

 

Froude’s number

 

Froude’s number is defined as square root of ratio of inertia force of flowing fluid to gravity. It is denoted as Fe
