Express the Bernoulli equation in three different ways using (a) energies, (b) pressures, and (c) heads.

What is the hydraulic grade line? How does it differ from the energy grade line?

What is the difference between pitot tube and pitot static tube?

A piezometer and a Pitot tube are tapped into a 4-cm diameter horizontal water pipe, and the height of the water columns are measured to be 26 cm in the piezometer and 35 cm in the Pitot tube (both measured from the top surface of the pipe). Determine the velocity at the center of the pipe.

A pipe of diameter 400 mm carries water at a velocity of 25 m/s. The pressures at the points A and B are given as 29.43 N/cm2 and 22.563 N/cm2, respectively while the datum head at A and B are 28 m and 30 m. Find the loss of head between A and B.
