I was bored because I had to study fluid mechanics. But strangely, after watching this video I became interested in it. This man surely knows how to teach.
These videos are so clear and simple - Thank you. The problem I am having is that you need to know the velocity to find the Reynolds number, and then to find that f= 0.03, so you can estimate the velocity. This appears to be a circular problem where we need to know the velocity before finding it.
This is true. However, if you have a very rough idea of the velocity, you can then estimate f. Most pipe systems operate under highly turbulent flow somewhere between Re=10,000 and 100,000. And within this range, there is not a massive difference in the f value if you look at a Moody Diagram. SO by making a few assumptions, you could get a reasonable estimate of the velocity.

Thanks, glad it helped!

@@fluidsexplained1901 Thanks for your reply. I have done just that and iterated with some simple code and get the answer I'm looking for.
@@fluidsexplained1901 So where did you get the rough estimate of velocity? Did you get it from the ideal flow state which was it 0.358 L/s?
@@mondomeccano Can you show me how you did it?
Is it safe to assume there are no exit losses in this system as the pipe discharges to the atmosphere?
Yep!
