Kg/m3). In ES units (English System of Units) the density is in slugs per cubic foot, ρ (Slug/ft3). Specific weight γ is related to density through Newton’s second law of motion, Force = Mass × Acceleration. 81 m/s2 when using SI units. , γ (lb/ft3). 1. The weight of a fluid causes pressure to increase with depth. , independent variable) that has its origin on this surface and is positive downward. 589 (lb · s/ft ) 2 5 μ × 10 Abs. 4c) and In the last equation, the pressure p assumes that atmospheric pressure is the reference base pressure, and therefore p is gage pressure.

Fluids, such as water, whose absolute viscosities are not dependent upon the rate of shear, ∂v/∂n, are referred to as Newtonian fluids. 1. , μ(∂v/∂s) or μ(τ)) then the fluid is referred to as a non-Newtonian fluid. , bounces as a rubber ball), but flows as a very viscous fluid if given sufficient time to do this.

6 Subcritical, Critical, and Supercritical Flows An open-channel flow is classified according to how the average velocity, V, of the flow compares with the speed, c, of a small amplitude gravity wave in that channel. If V is less in magnitude than c, then the flow is subcritical. If V is greater in magnitude than c, then the flow is supercritical, and if V = c, then the flow is critical. 1) where g is the acceleration of gravity A is the cross section of the flow T is the top width of the flow Yd is the hydraulic depth, A/T Subcritical flows behave differently from supercritical flow because in a subcritical flow the effect of downstream changes are noted by the fluid and it adjusts in anticipation of that downstream occurrence.
