Hello students, here some fill up the blanks are given.
00:03
We have to answer them.
00:05
First, as a group liquids and gases are referred to as fluids.
00:13
The ratio of density of substance to the density of water is specific gravity.
00:24
Third one, the si unit of pressure is pascal.
00:31
Fourth, an object placed in a fluid is lifted up by a force called buoyant force.
00:44
An immersed object is buoyed up by a force equal to the weight of the dash fluid that is displaced fluid.
00:57
Sixth, the volume of fluid flowing per unit time is rate of flow.
01:07
Seventh, bernoulli's principle states that when the velocity of fluid is high, the pressure will be low.
01:16
The equation called dash continuity equation relates the cross section area and velocity.
01:23
The equation is area into velocity is equal to constant.
01:30
Ninth one, the viscosity of fluid is due to friction...
