An ideal liquid flows through a horizontal tube of variable diameter. The pressure is lowest where the _____.

Step-by-step solution

Using Bernoulli's theorem, which states the total mechanical energy, potential energy and kinetic energy of an ideal and steady fluid flow remain conserved at a section during flow process. ⇒ P ρ + v 2 2 + g h = constant P   is the pressure of fluid at the section, v   is the velocity of fluid at that section and h   is the height of fluid flow. P ρ → pressure head v 2 2 → velocity head g h → elevation head According to Bernoulli's theorem, total head remain
