Fluids Flashcards
average pressure on side wall
1/2 rho h g
Accelerating fluids , the formula for tan theta(theta being the angle made by the water level with the horizontal level)
Rotating fluids formulae
Paraboloid and cylinder volume
Equation of continuity expression
Reynolds number equation +relations
bernaulli’s equation
Speed of efflux formulae plus what will be maxed if the beaker is kept on flat ground or kept on an edge
if the beaker is kept on an edge, the max will be when the holes at the bottom-most point
and if its on flat ground
it will be maxed when it is in the h/2 of the beaker
bouyant force formula
V rho g
relation between F1 , A1 , F2 , A2
F1A1=F2A2
Viscous force formula(between the layer’s one)
Venturimeter formulae
Stokes law
Terminal velocity formula
what are cohesive and adhesive forces?
cohesive forces are the force of attracting between molecules of same substances
adhesive forces are the forces of attracting between molecules of different substances
surface tension formula and the direction of the force?
What’s the surface energy formula?
What’s the surface energy applied to bubbles in the air?
2S
how can we find the energy released/heat temperature changed in forming a coalesce?
excess pressure in liquid drop and bubble in air?
excess pressure on the bubble in water?
because only one side is in contact with air and has a surface tension
the formula for the radius of coalesce of two bubbles in contact(externally)?
the formula for the radius of coalesce of two bubbles in contact(internally)?
force needed to seperate two glass plates with liquid in between them
capillary action thin tube formula
