Chapter 4

Question 1

density equation

Answer 1

ρ = m / V

m = mass

v = volume

Question 2

weight of a volume of fluid

Answer 2

F = ρVg

F = buoyant force
ρ = density of liquid
g = acceleration due to gravity (9.8)
V = fluid volume

Question 3

pressure equation

Answer 3

P = F / A

P = pressure

F = magnitude of the force

A = area

Question 4

absolute pressure (pressure in a fluid) equation

Answer 4

ρ = density of liquid
g = acceleration due to gravity (9.8)
h = depth below the surface
