Hard Stuff Test 1

Question 1

Henrys law

Answer 1

c = K x ρ where c = concentration of gas that is absorbed (e.g., milliliters per liter), ρ = partial pressure gas exerts, K = solubility factor (Henry’s constant) differs from gas to gas.

Question 2

What effects solubility and how

Answer 2

Direct

• -altitude
• -water pressure

Indirect
–temperature

Question 3

Oxygen hetrograde

Answer 3

Positive–> O2 super saturation Bellow meta

Negative–> Minimum amount of O2 ABOVE the meta

Question 4

Reynolds Number (Re)

Answer 4

standard measure in fluid mechanics of the ratio of inertial
and viscous forces in a flow

Re = p U L / u
p–> density
U–> relative velocity
L–> linear dimension(cm)

u–>dynamic viscosity

Flow is laminar when Re is low

Question 5

Whiting

Question 6

Extinction coefficient

Answer 6

fraction (%) of light absorbed per meter of water.

learn the equation (heat)

Question 7

Relative Thermal Resistance

Answer 7

function of the density difference between the top and bottom of a defined thickness of water

RTR = (D2 - D1) x 10^6 /8

Question 8

Richardson’s number (Ri)

Answer 8

ratio of work done by stirring to overcome the stabilizing buoyancy force

buoyancy/ mixing
