Bernoullie's equation is the fundamental equation in fluid dynamics that relates pressure of fluid to its speed and height .According to Bernoulli's equation, when the speed of the fluid is high, then the pressure will be
Correct answer: A. Low
- A. Low
- B. Zero
- C. High
- D. Constant
Explanation
According to Bernoulli's equation, when the speed of a fluid increases, the pressure within the fluid decreases. This is because Bernoulli's equation describes the conservation of energy in a flowing fluid, where an increase in kinetic energy (speed) results in a decrease in potential energy (pressure). Therefore, option A is correct. Option B is incorrect as pressure typically does not become zero. Option C is incorrect as the pressure does not increase with speed. Option D is incorrect because pressure does not remain constant when speed changes.

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.
