3. FLUID
• Fluid is a substance that continuously deforms with shear force.
Examples:

4. TYPES OF FLUIDS
• Steady fluid: It is the fluid whose density remains constant at each
and every point while flowing.
• Unsteady fluid: It is the fluid whose velocity differs between any two
points while flowing.
• Compressible fluid and incompressible fluids: These are classified
based on the Mach Number. The incompressible fluid has Mach
Number<0.3 and the compressible fluid has Mach Number between
0.3 and 1.

5. Multiphase
• Two (or) more distinct phases flowing simultaneously in the mixture,
and
• Have some level of phase separation at a scale well above the
molecular level.
For example, Different-sized solid particles of the same material can be
treated as different phases because each collection of particles with the
same size will have a similar dynamic response to the flow field

6. TYPES OF MULTIPHASES
• Solid
• Semi-solid
• Liquid
• Gases

7. HANDLING OF FLUIDS
• Liquid in relative motion is similar to the handling of fluids.
1) Motion along the Horizontal plane/track
• tan 𝜃 =
ℎ1−ℎ2
𝑙
• tan 𝜃 =
ℎ1−ℎ2
𝑙
=(𝛼𝑋)/𝑔
• Where,𝛼𝑥=Accuration
• g=gravity

8. 2)Motion along the incline plane:
a)tan 𝜃 =
ℎ1−ℎ2
𝑙
=(𝛼𝑥)/(𝑔 ± 𝛼𝑧)
Where, 𝛼𝑥 = +𝑐𝑜𝑠𝜃
here, 𝛼𝑧 = − sin 𝜃

9. • Motion along the Vertical plane
• 𝑝 = 𝑒𝑔ℎ[1 ±
𝛼 𝑍
𝑔
]
• The If container moving downwards with𝛼𝑧=g,
• Then at point on the container , the
pressure will be Zero(container falling freely)
