   Hi
   Attached is an extract of a paper by Lord Rayleigh on pressure generated during collapse of a bubble in a liquid. Will someone please explain how the RHS of equation (2) in the attachment is obtained ?
   
   TIA

   Use eq (1) to Substitute [itex] \frac{UR^2}{r^2} [/itex] for [itex] u [/itex] in the integral. Doesn't the integration work out after that?

   Thank you. Got it now. On hindsight, what a silly question to ask.
   
   Thanks again
