An addendum. I intend to measure the cross sectional area of the stream using the shadows it casts on a surface, since measuring the stream diameter would be very hard.
However, here I encounter another problem, the shadows become indistinct as I cast them on the wall, and are useless to my...
I was wondering if anyone could point me towards a source about making constant head devices. I was wanting to measure and then relate, experimentally, the velocity of a stream to its cross-sectional area. Since this will be done mostly at home using pedestrian tools, I need to find out how I...
