Question
Plasma beta is a ratio of two analogs of this quantity, one of which equals B-squared over two-mu-nought. This quantity is recorded in the lower three diagonal elements of the stress–energy tensor. This quantity ceases to decrease when a system reaches choked flow, which is a breakdown of its decrease with cross-sectional area in the Venturi effect. A transducer measures the difference of two forms of this quantity to calculate flow speed in a (*) Pitot ("PEE-toh") tube. A "stagnation" form of this quantity equals the sum of its "static" and "dynamic" forms. The sum of three forms of this quantity, including one written "rho-g-h," is constant via Bernoulli's principle. For 10 points, name this quantity measured in bars or pascals. ■END■
ANSWER: pressure [or fluid pressure; accept plasma pressure or magnetic pressure; prompt on P; prompt on energy density or normal stress]
