Fluid dynamics

Question 1

Pressure in a liquid

Answer 1

dP = gpdH

pressure, 9,81, density, hight

Question 2

bernoulli constant

Answer 2

constant = P/p + o.5* v^2 + g*h

Question 3

Venturi (You have to derive this)

Answer 3

P1-P2 = 0.5 * p * (((A1/A2)*v1)^2 - v1^2)

Question 4

Pitot (derive this)

Answer 4

v = sqrt((2* dP)/p)
