[QUOTE="Callmelucky, post: 6852802, member: 730227"] [B]Homework Statement:[/B] Theory not task [B]Relevant Equations:[/B] ##p1+\frac{\rho(V1)^2} {2}=p2+\frac{\rho(V2)^2}{2}## Can you please explain why is there work done by F2(on photo of textbook explanation of Bernoully equation (photo below)). I can understand that W2 is caused by F2 which is gravitational force(screenshot photo from YT). But for the explanation in textbook pipe is straight, no height difference, so what causes F2? Is it the part of pipe that gets narrower(that "blocking affect", but shouldn't that be the cause for greater speed v2 compared to v1)? Fluid in both cases(photos) is moving from left to right. In textbook it's said that F2 is caused by surrounnding fluid, but how? If fluid is moving towards right side? And fluid is ideal(no resistance, not compressible). Thank you. [/QUOTE]
