Introduction to Compressible Flow - University of Utah

In most flows of liquids, and of gases at low Mach number, the density of a fluid parcel can be considered to be constant, regardless of pressure variations in the flow. Therefore, the fluid can be considered to be incompressible, and these flows are called incompressible flows. Bernoulli performed his experiments on liquids, so his equation in its original form is valid only for incompressible flow. A common form of Bernoulli's equation is: WebFFS = 70 – fLW – fLC – fN - fID Where FSS = estimated free-flow speed fLW = adjustment for lane width fLC = adjustment for right-shoulder lateral clearance fN = adjustment for number of lanes fID = adjustment for interchange density The adjustment factors can be obtained from the tables below.
