**Uniform Flow:**

If the fluid properties like density, velocity and pressure, etc. do not change throughout the fluid flow, then this type of flow is called uniform form.

**Mathematically, it can be written as-**

V ⃗ = V (t)

P = P (t)

ρ= ρ (t)

Or,

[∂V/∂s]t= constant = 0

[∂P/∂s]t= constant = 0

[∂ρ/∂s]t= constant = 0

**Non-Uniform Flow:**

If the fluid properties like density, velocity and pressure, etc. change throughout the fluid flow, then this type of flow is called non-uniform form.

Mathematically, it can be written as-

[∂V/∂s]t= constant ≠ 0

[∂P/∂s]t= constant ≠ 0

[∂ρ/∂s]t= constant ≠ 0
