For flow through a pipe of radius R, the velocity and temperature distribution are as follows: u(r,x) = C1, and T(r,x) = C2[1 - (r/R)3], where C1 and C2 are constants. The bulk mean temperature is given by Tm = (2/(UmR2)) ∫0R u(r,x)T(r,x)rdr, with Um being the mean velocity of flow. The value of Tm is
