State Bernoulli's theorem for an ideal liquid flowing through a horizontal tube.

Expert Answer:

According to Bernoulli's theorem,

P/ρ + gh + ½v² = constant                     ......(1)
For a horizontal tube, the two ends of the tube will be at the same level (there will be no level difference)
Therefore h = 0
From equation (1), we get
P/ρ + ½v² = constant
Thus, Bernoulli's theorem states that in the streamline flow of ideal liquid through horizontal tube, the sum of pressure energy per unit mass and kinetic energy per unit mass remains constant at any cross-section throughout the flow.
