Fluid mechanics

Question 1

Pressure

Answer 1

P = F/A

Question 2

Pressure at depth

Answer 2

P = P₀ + ρgh

Question 3

Bouyant force

Answer 3

B = ρ_fluidgV

mass of fluid displaced * gravity

Question 4

density/volumn relationship for partially submerged object

Answer 4

Fg = B
ρ_fluidgV_fluid = ρ_objgV_obj
V_fluid/V_obg = ρ_obg/ρ_fluid

Question 5

fluid continuity equation

Answer 5

A₁v₁ = A₂v₂

Question 6

Bernoulli’s equation

Answer 6

1/2*ρ*v² + ρ*g*h + P = constant
