compute the volume of a tap stream?

Question

I have a video of the free flowing stream from a tap. based on video/video images, how do i compute the volume of the stream? any idea?

Thank you Morkeleb. but the stream is not exactly cylindrical. It is turbulent with splashes, and sputters. Any ideas will be highly welcome.

Answer 1

I think what you are asked for is the volumetric flow rate.

Follow a drop on video. approximate the time it takes for the drop to reach the bottom of the image. Take a ruler and measure the width of the tap. Also measure the length of the stream from the tap to the bottom of the image.

Assume the stream is cylindrical. Calculate the volume of the stream using [h(pi)d^2]/2 where h is the measured height of the stream and d is the measured witch of the stream. That much volume gets filled up by water in the measured amount of time. Therefore divide your volume by the aproximated time to find the volumetric flow rate of the stream.

Your answers should be in m^3/sec

Answer 2

Draw the two parabolas. They of course meet at (0, 0) and (a million, a million). The horizontal line at a given y cuts the two curves at (y², y) and (?y, y); so the slice of the forged of revolution cut back by using the plane at a given y is an annulus with outer radius a million-y² and inner radius a million-?y, and its section is ?(a million-y²)²-?(a million-?y)². improve and combine this from y=0 to a million!

Answer 3

Isn't the volume of a cylinder [h(pi)d^2/4]?
