A fluid with specific gravity 0.85 is flowing through a diameter 250 mm and 150 mm at the bottom and upper ends respectively. Determine the difference in datum head if the rate of flow through pipe is 0.04 m3/s. Take pressure at top and bottom as 27 N/cm2 and 10 N/cm2.

Water is flowing through a pipe of 3.8 cm diameter under a pressure of 20 N/cm2 (gauge) and with mean velocity of 3.7 m/s. Find the total head or total energy per unit weight of the water at a cross section, which is 7 m above the datum line.

In derivation for Euler s equation, the weight of fluid element is considered as negligible and ignored in calculation.

According to statement of Bernoulli s theorem if Kinetic or Potential Energy is changing then overall energy changes and hence energy is not constant at all the places.

If in a fluid, while applying Newton s second law of motion, compressibility force is neglected then what equation is obtained?

From mathematical perspective if for a fluid curl of velocity vector is some constant value, it is ideal, steady and incompressible, then we can apply Bernoulli s equation.

Which of the following assumption is incorrect in the derivation of Bernoulli s equation?

In order to apply Bernoulli s equation across two sections, we have to obtain it from Euler s equation. What is the operation that needs to be carried out in order to obtain it from Euler s equation?

Navier-Stoke s equation can be obtained from Reynolds s equation by not considering which type of force?

Which forces are neglected to obtain Euler s equation of motion from Newton s second law of motion?
