Newtonian Fluid: A fluid whose viscosity doesn't depend on gradients in flow speed. Gases and low-molecular weight liquids are usually Newtonian fluids.
Non-Newtonian Fluid: A fluid whose viscosity changes when the gradient in flow speed changes. Colloidal suspensions and polymer solutions like ketchup and starch/water paste are non-Newtonian fluids.
Interstitial Fluid: Fluid surrounding the cells in body tissues; provides a path through which nutrients, gases, and wastes can travel between the capillaries and the cells.
Masking Fluid: A latex gum product that is used to cover a surface you wish to protect from receiving paint. Miskit by Grumbacher and Art masking fluid by Winsor & Newton are two such products. Also referr . . . View Full Definition
Supercritical Fluid: A fluid state that occurs when the pressure and temperature exceed the substance's critical pressure and critical temperature. Supercritical fluids fill their containers like gases but disso . . . View Full Definition
Thixotropic Fluid: A liquid that becomes less viscous when stirred. Paint and printing inks are thixotropic fluids; they are formulated so that they flow more freely when brushed or rolled.
Synovial Fluid: The clear fluid that lubricates and protects a joint and its surface.
Fluid-Mosaic: Widely accepted model of the plasma membrane in which proteins (the mosaic) are embedded in lipids (the fiuid).
