Member warned that homework questions must be posted in a homework section
Hi everyone,
I have to answer some question about a physics lab..here are the questions
A tank is empty by a pipe and we measure the height (y-y0) of fluid in the tank as a function of time. We obtain this graph ( I join the graph)
We can find the relaxation time
with the relation :
with (yin -y0) is the initial height of the fluid in the tank and (y-y0) is the height of the fluid at a time t.
I can easily isolate
but the teacher say that it's a part of the graph which is the best to evaluate
.
He ask what is this part and why ??
It's a physics lab about the fluid flow and poiseuil equation for viscosity...
If someone can give me some track ..
Sorry for my English I'm French..
