Fluids Formulas

Question 1

Density

Answer 1

density = △m/△v

Question 2

Fluid pressure

Answer 2

pressure = △F/△A

Question 3

Pressure Variation with height and depth

Answer 3

p2 = p1 + density (y1 - y2)
p = p0 + density (gh)

Question 4

Archimedes principle

Answer 4

buoyant force = mass of the fluid x gravity
apparent weight = weight - buoyant force

Question 5

Flow of Ideal Fluids

Answer 5

Rv = Av = constant
Rm = density (Rv) = density Av = constant

Question 6

Bernoulli’s Equation

Answer 6

p + 1/2 ρv^2 + ρgy = constant
