Cohesion and Adhesion in Liquids: Surface Tension and Capillary Action
An ideal fluid is incompressible and has no viscosity
How do cohesive and adhesive forces affect the behavior of fluids?
Viscosity: Cohesive & Adhesive Forces
Define surface tension.
Ideal fluids are:
Incompressible – the density is constant
Irrotational – the flow is smooth, no turbulence (Laminar)
Nonviscous –(Inviscid) fluid has no internal friction ( η = 0)
TED-Ed: How blood pressure works
If you lined up all the blood vessels in your body, they’d be 60 thousand miles long. And every day, they carry the equivalent of over two thousand gallons of blood to the body’s tissues. What effect does this pressure have on the walls of the blood vessels? Wilfred Manzano gives the facts on blood pressure.
