14 Questions around this concept.
The dimensional formula of angular velocity is equal to?
Fluids-
Fluids are the substances which began to flow when an external force is applied to it.
Fluids examples are liquids and gases.
Fluids don't have their own shape but they take shape of the containing vessel.
In Hydrostatic branch we study fluids which are at rest with respect to containing vessel.
While in Hydrodynamics we study fluids which are in motion with respect to containing vessel. For example study of flowing water from the tap comes under Hydrodynamics.
Ideal fluids- Assumption
It is Incompressible- Means the density and the specific volume of the fluid do not change during the flow.
It is Non-viscous- Layers of fluids does not exert any tangential force (especially friction force) on each other. And A true "non-viscous" fluid would flow along a solid wall without any slowing down because of friction
Pressure-
1. Normal force exerted by liquidfluid at rest per unit Area of the surface is called pressure of a liquidffluid.
If
2. Units of pressure is
3. The dimension of pressure is
4. Atmospheric pressure- The pressure exerted by the atmosphere is called atmospheric pressure. 1 atm is the value of atmospheric pressure on the surface of the earth at sea level.
And
So Relation between bar and Pascal is 1 bar
