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

The lord gave the knights a piece of land called fief and promised to protect it. The fief could be inherited. The knight might serve more than one lord but his foremost loyalty was to his own lord. In France ,from the twelfth century, minstrels travelled from manor to manor, singing songs which told stories -partly historical partly invented -about brave kings and knights. Many manors had a narrow balcony above the large hall where the people of the manor gathered for meals
