The effect of the decrease in pressure with the increase in speed of the fluid in the horizontal tube gives
Correct answer: B. Bernoulli's effect
- A. Torrielll's effect
- B. Bernoulli's effect
- C. Venturis effect
- D. Doppler effect
Explanation
Bernoulli's principle states that as the speed of a fluid increases, the pressure exerted by the fluid decreases. This principle applies to the flow of fluids in various situations, including in horizontal tubes. When the fluid flows through a tube and its speed increases, the pressure decreases.

About Bernoulli's Equation
Bernoulli’s equation applies conservation of energy to steady flow of an incompressible, non-viscous fluid along a streamline: pressure, kinetic and gravitational terms have a constant total. It explains pressure-speed changes in narrow pipes, Venturi meters and lift, and differs from continuity because it relates pressure as well as velocity and height.
