    WATER HAMMER / FLUID HAMMER/HYDRAULIC SHOCK / WATER BLOW

    WATER HAMMER / FLUID HAMMER/HYDRAULIC SHOCK / WATER BLOW Water hammer is also called a fluid hammer or Hydraulic Shock’ or a water blow.  It largely takes place in liquids but to a limited extent it can also be present in gases. It is a very high pressure wave created due to sudden change in […]

    : FLUID MECHANICS: BERNOULLI EQUATION AND MOMENTUM EQUATION

    FLUID MECHANICS: BERNOULLI EQUATION AND MOMENTUM EQUATION Bernoulli Equation The Bernoulli equation comes from Newton’s law of motion. Assumptions used in deriving Bernoulli’s equation: Flow is steady Incompressible flow Non-viscous flow (ideal fluid with zero viscosity) No losses and no energy exchanges Bernoulli’s equation states that “Total head of a flowing fluid is constant or […]
