FLUID STATICS No flow

FLUID STATICS No flow Surfaces of const P and r coincide along gravitational equipotential surfaces. h = head = scalar; units of meters = energy/unit weight (energy of position). P = 1 atm surface P ~ 1.3 atm @10 feet P ~ 1.6 atm @20 feet

Chapter 14

Chapter 14. Fluids. Fluids at Rest. (Fluid = liquid or gas). Density ( r ). unit: kg/m 3 we will consider only r = m / V = constant (incompressible fluid) we will also assume g = constant. Pressure ( p ). A fluid exerts a force dF normal to any area dA you consider in it.

A fluid is (a) a liquid. (b) a gas. (c) anything that flows.

A fluid is (a) a liquid. (b) a gas. (c) anything that flows. (d) anything that can be made to change shape. (e) All of the above. In the drawing on the right, the dotted line represents the volume of fluid equal to the volume of the object on the right.
