Bernoulli’s Principle

  • For a streamline fluid flow, the sum of the pressure (P), the kinetic energy per unit volume (ρv2/2) and the potential energy per unit volume (ρgh) remain constant.
  • Mathematically:- P+ ρv2/2 + ρgh = constant
    • where P= pressure ,
    • E./ Volume=1/2mv2/V = 1/2v2(m/V) = 1/2ρv2
    • E./Volume = mgh/V = (m/V)gh = ρgh
