Answer to Question #106594 in Physics for Thomas

Question

Find the hydrostatic and absolute pressure exerted on an object that is 4.45m below the surface of gasoline. The density of gasoline is 680 kg/m3

Answer 1

hydrostatic pressure is determined as follows

$P.hydrostatic = \rho * g * h = 680 * 9.81 * 4.45 = 29,685 Pa$

Absolute pressure is the total of atmospheric and hydrostatic pressure

$P.absolute = P.hydrstatic + P.atmosphere = 29,685 + 100,000 = 129,685 Pa$
