Consider fully-developed, laminar flow in a circular pipe. i) Following a procedure similar to the one used in question 1, perform a control volume analysis over an annular fluid volume of thickness dr, x-length dx. Please include a detailed sketch. Obtain a relation between dTrx/dr and dp/dx.
ii) Substituting Trx = mu(du/dr) and integrating between r = 0 and r = R, obtain u(r).
