when in equilibrium, fluids cannot sustain tangential forces

fluids are capable of flowing

when in equilibrium, fluids can sustain shear forces

fluids conform to the shape of the con-taining vessels

Local atmospheric pressure is always below standard atmospheric pressure

Local atmospheric pressure depends upon elevation of locality only

A barometer reads the difference be-tween local and standard atmospheric pressure

Standard atmospheric pressure is the mean local atmospheric pressure a* sea level

only when the fluid is incompressible and has zero viscosity

irrespective of the motion of one fluid layer relative to an adjacent layer

only when the fluid is frictionless

When there is no motion of one fluid layer relative to an adjacent layer
