Questions & Step-by-Step Solutions

Which of the following equations represents Bernoulli's principle?
  • Step 1: Understand that Bernoulli's principle deals with fluids (liquids and gases).
  • Step 2: Know that the principle relates three main factors: pressure (P), velocity (v), and height (h) of the fluid.
  • Step 3: Recognize that the equation combines these factors into one formula.
  • Step 4: The equation is: P + 1/2 ρv² + ρgh = constant.
  • Step 5: In this equation, ρ represents the density of the fluid.
  • Step 6: The term 1/2 ρv² represents the kinetic energy per unit volume of the fluid.
  • Step 7: The term ρgh represents the potential energy per unit volume due to height.
