SUMMARY

The discussion centers on the pressure differences between two pipes with varying diameters, specifically a 1 m diameter pipe (pipe A) and a 0.5 m diameter pipe (pipe B). According to the continuity equation, the velocity of fluid in pipe A is lower than in pipe B due to the larger cross-sectional area. Applying Bernoulli's equation confirms that the pressure in pipe A is higher than in pipe B, as pressure and velocity are inversely related in fluid dynamics.

If a pipe separates into 2 pipes, one with 1 m diameter (pipe A), and the other 0.5 m diameter (pipe B)... which tube has the higher pressure.

From the continuity equation, we know that velocity decreases as area increases. So I know that pipe A has lesser velocity than pipe B.

And now using Bernoulli's equation what do you find?
