I will gather all this data and write the equations, then tie it to a 2D heatmap at certain times, then compare the theoretical and experimental values. Thanks for all the feedback

The tube was made from some kind of plastic. Not sure which. It wasn't thick plastic, so the difference between ID and OD isn't much. I didn't get specific measurements (and I don't have access to the tube anymore), but if I had to assess the value from memory, it would be around (2 - 4) mm

Thanks for all the replies, first of all, IRL means In Real Life :) We used 8x25W (connected in parallel) lightbulbs so 200W combined. I'm sure that the x (time) axis is in seconds, seeing how the experiment went on for about 15minutes. We stopped there because we ran out of time assigned...

Ah yes sorry. I have the information but I seemed to forget to write it here. 1. The tube is horizontal. No inclination. 2. Diameter of the tube is (15.0±0.1)cm, its length is (2.50±0.05)m 3. The first batch of sensors are about 5cm away from the sensors, the second batch are about 1.5m away...

TL;DR Summary: Help needed with plotting heat maps, using data we gathered in an experiment. Hello, so I'm having problems with analysing data, which we gathered from an experiment we did in class. This is meant as a type of non-guided experiments class, where we are just given an initial...

I just had a quick glance over them and yes! They will definitely help. Thank you very much

Will try that for sure sometime next week. Got more pressing stuff to deal with for now. Thanks for the suggestion

Okay so today I went to my prof., and I showed him how I approached the problem. We derived the same equations we got here together, and I asked him how he would go on to get the oscillation time. He said that I definitely need to solve this numerically, as someone already suggested. He...

Actually, I already had that term included when I was first asking the question (also wrote it in), but then most of you said it shouldn't be in, although I am still conflicted about it. On one side it tells you the rate of change of mass, but on the other change in mass is already considered in...

I tried to duplicate the experiment (quickly) at my home - so I would pay more attention to the water flow. It wasn't an accurate experiment, but yes, I believe treating the leaving water as static drain should be fine. However I don't understand where you got ##\dot h = - \rho \sqrt{gh}##...

Great ! Thank you very much

Thanks for the reply, and yes I'm not so sure about that term either (not so experienced as well :P). But seeing both mass and velocity are functions of time, and you differentiate over time, I would expect that the (dm/dt) * (dx/dt) is also present. Plus it makes sense you have a term that...

Hello, So about two weeks ago in class we looked at RLC circuits in our E&M course, and short story short... we compared the exchange of energy between the Capacitor and the Inductor (both ideal) to simple harmonic motion. Once the capacitor and inductor are not ideal anymore, we said it's...

Hi, My name is Tine, and I'm a first year Physics undergrad student. Keen to keep learning about this beautiful system we live in :)
