Homework Statement
Water flows with a speed v down a rectangular pipe of dimensions s and l as shown. What is the rate [itex]\Phi=volume\, per\, unit\, time [/itex]
at which water accumulates in the bucket?
Homework Equations
[itex]\Phi=\int_S\mathbf{v}\cdot d\mathbf{a}[/itex]
The Attempt at a Solution
I am confused as to how to compute this integral. I do not see how could use the divergence theorem to simplify it since I only have the dimensions of the 2-dim surface of the rectangular pipe.
I am not sure how to evaluate the surface integral based solely on its definition. Can someone help to get me started?
Do I just use the definition [itex]\Phi=\int_S\mathbf{v}\cdot d\mathbf{a}[/itex] for this?
