WebApr 6, 2024 · We expect the pressure drop to be 1 over (⅔)^4.9 or about 7 times higher than the original pipe. At 0.3 gpm, the pressure drop is 3 inches. That’s about 6 times the original. At 0.6 gpm, the pressure drop is 7.5 inches, about 7 times the original. And at 0.9 gpm, we’re off the scale.

WebJan 21, 2024 · Consider a pipe with length L and uniform radius A is held vertically. According to the continuity equation, the velocity of water going into the pipe seems to be the same as the velocity of water coming out. But according to Bernoulli's equation: P a t m + 1 2 ρ v 1 2 + ρ g L = P a t m + 1 2 ρ v 2 2 v 2 = v 1 2 + 2 g L WebThere are basically two ways to make fluid flow through a pipe. One way is to tilt the pipe so the flow is downhill, in which case gravitational kinetic energy is transformed to kinetic energy. The second way is to make the pressure at one end of the pipe larger than the pressure at the other end. philstar fact check
