Saturated waste steam at 40oC, flows in the outer tube of a double-pipe heat exchanger, and condenses on the surface of the inner tube, which is thin-walled, 3-cm in diameter, oriented horizontally and made of copper. Cooling water flows through the inside tube at 2 m/s, entering at 25oC and exiting at 35oC. Determine: Mass flow rate of the cooling water in the inner tube (kg/s) (5) Rate of heat transfer from condensing steam to the cooling water (kW) (5) Reynolds number in the tube to verify turbulent flow. (5) Heat transfer coefficient on the inside of the inner tube using the Sieder-Tate equation, ignoring the viscosity correction. (15)
