Ethylene glycol is passed at $6\frac{m^3}{s}$ through the tube. The inner radius of the tube is $0\mathrm{.}03m,$ tube length is $10m,$ and it is made out of commercial steel. The outer radius of the tube is $0\mathrm{.}04m.$ On the outer surface of the tube is condensing steam at $130C.$ The ethylene glycol enters the tube at $10C$ and leaves at $25C.$ How much heat is exchanged in this process? You may assume that the fluid flow obeys the following relationship $($average values for St and Cf are used$)$:
