Hydraulics and Fluid Mechanics in ME The Bernoulli's equation is based on the assumption that No force except gravity acts on the fluid There is no loss of energy of the liquid flowing All of these The velocity of flow is uniform across any cross-section of the pipe No force except gravity acts on the fluid There is no loss of energy of the liquid flowing All of these The velocity of flow is uniform across any cross-section of the pipe ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The error in discharge (dQ/Q) to the error in measurement of head (dH/H) over a rectangular notch is given by dQ/Q = (1/2) × (dH/H) dQ/Q = (3/2) × (dH/H) dQ/Q = (3/4) × (dH/H) dQ/Q = (dH/H) dQ/Q = (1/2) × (dH/H) dQ/Q = (3/2) × (dH/H) dQ/Q = (3/4) × (dH/H) dQ/Q = (dH/H) ANSWER DOWNLOAD EXAMIANS APP
Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly enlarged to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden enlargement is (v₁ - v₂)²/g (v₁² - v₂²)/g (v₁ - v₂)²/2g (v₁² - v₂²)/2g (v₁ - v₂)²/g (v₁² - v₂²)/g (v₁ - v₂)²/2g (v₁² - v₂²)/2g ANSWER DOWNLOAD EXAMIANS APP
