Tossup

For flows displaying this property, the Navier–Stokes equation reduces to Burgers’s equation. The pressure is often described as a Lagrange multiplier that enforces this property, which causes the Langevin (“lanj-VAYN”) equation to contain a transverse projection operator. The n equals zero polytrope has an interior with this property. An approximation (-5[1])named for a pseudo (-5[1])form of this property can be derived solely by assuming small pressure perturbations. (-5[1])The simplest form of Bernoulli’s principle applies to flows with this property. Flows (10[2])with this property have small values of [read slowly] “one (-5[1])over density times the derivative of density with respect to pressure,” which is denoted (10[1])beta. (10[1])The divergence of the velocity (10[1])is zero (10[1])in flows (10[1])with (10[1])this (10[2])property, (10[4])as is the time derivative of density. For 10 points, name this property of fluids with a constant density. (10[1])■END■ (10[5]0[3])
