Question

please do all parts clearly

The Figure shows a shell and tube condenser where a vapor is condensing on the shell side due to heat removal by a coolant flulid whigh flows though the tubes. To analyze the steady state energy transport in this situation. We can focus on a single tube and apply the differential balance equation. Since the coolant is heated as it flows through the tube, we have both molecular and convective energy transport in the flow direction. The inner and outer cylinders have radii of Ri and R respectively. The surface of the outer cylinder, which is constant at Tw.
