I can't even approach this question. Any ideas on how to write the equations?

# Doubt from heat transfer

Got it..

How?

Due to network issue cant upload..will do it by night.

Ok.

Is the answer 11 sec?

I mean 10+x=11

Yeah. How?

COPY PASTE.

Assume that B is at any radial distance x

Mag of velocity = √ radial^2 + tangential ^2

Now the omega of A = w of B

So tangential velocity = wx

Now u get function of radial velocity as a function of radius..

Integrate from 0 to r
