Equação de Bernoulli III: Tubo Venturi

Chapter IV - Fluid Dynamics This video demonstrates how to use Bernoulli's Equation to calculate the pressure difference and consequently the static height difference of a manometer in Venturi tubes, solving the following exercise: In the Venturi tube, kerosene (δ = 0.85) flows with the area of ​​section (1) being 24 cm2 while that of section (2) is 12 cm2. The velocities of the kerosene in sections (1) and (2) are 4.5 m/s and 9 m/s respectively. A manometer whose manometric fluid is mercury (δ = 13.586) is connected between the two sections and indicates a level difference “h”. Calculate the value of the level difference “h”.
