[A small panel only with text. Written as an excerpt from a mathematical text book. Begins with a number for an equation, then follows the equation written in larger letters and symbols. And below are explanations of each term in the equation. The μ has a bar over the top and the D has a double vertical line.]

Eq. 4-15

T = 𝔻m0(rout - rin)μ̅

T: Net rate

m0: Unit mass

(rout-rin): Flow balance

𝔻, μ̅: Decorative
