Q5: Cooling water at a steady rate of 0.5 kg/s flows through an inner tube having inner diameter of 25 mm and length of 10 m of a tube in tube condenser. The mean inlet temperature of cooling water is 10°C. Saturated steam condenses in the annulus at a uniform rate such that the inner surface temperature of the tube is constant throughout the length of the tube at 40°C. The average condensing side heat-transfer coefficient is 10000 W/m2 K. Neglect the thickness of the heat exchanger tube. Calculate the effectiveness of the heat exchanger and the exit water temperature. Properties of water are: ん Specific heat 4180 J/kg K ,Dynamic viscosity 0.8 x 10 Pas and %3D Thermal conductivity 0.57 W/m K.
