How Does Fluid Velocity Compare at Different Points in a Siphon Tube?

    Tube Velocity
AI Thread Summary
In a siphon, the fluid's velocity at the top of the tube is related to the velocity of the exiting fluid at the bottom. Since no fluid is lost or created, the volume flowing in equals the volume flowing out, implying that the velocities must be equal if the tube's diameter remains constant. The discussion suggests that the term "velocity" may have been misused in the question, leading to confusion. The conclusion drawn is that the velocity at the top and bottom of the siphon tube is the same. Understanding these principles is crucial for accurately answering questions about fluid dynamics in siphons.

A siphon has been started, fluid is now flowing through it. What is the velocity at the top
of the tube in relation to the velocity of the exiting fluid:
(a) The velocity is greater at the top
(b) The velocity is less (but not zero) at the top
(c) The velocity is zero at the top
(d) The velocity is the same at the bottom

i'm not sure about this question...would anyone be able to explain the answer to me

No fluid is lost or created in the tube so the volume flowing in must equal the amount flowing out. If the size of the tube doesn't change what does this mean for the speed.

Unless this is a trick question - velocity is a vector it has magnitude and direction so walking north has a velocity of say 4mph north or -4mph south. I suspect that the word velocity was just misused in the question.
 
Therefore that makes the answer d then ?

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
