FLUID MECHANIC
FLUID IN MOTION
Above a certain speed, the flow becomes turbulent (
-
the pipe is wider, the flow is slower
PRESSURE ,DEPTH AND PASCAL LAW
PASCAL PRINCIPLE
If an external pressure is applied to a confinedfluid, the pressure at every point within the fluid increases by that amount
MEASUREMENT OF PRESSRURE
-
the pressure being measured will cause the fluid to rise until the pressures on both sides at the same height are equal.
The height of the column of mercury is such that the pressure in the tube at the surface level is 1 atm
-
EQUATION
BERNOULLI EQUATION
Where the velocity of a fluid is high, the pressure is low, and where the velocity is low, thepressure is high.

ρ of a substance is its mass per
unit volume:,
ρ = M/V
