Water flows at 5m/s is passed through a tube of 2.5 cm diameter, it is found to be heated from 20  °C to 60  °C. The heating is achieved by condensing steam on the surface of the tube and subsequently the surface temperature of the tube is maintained at 90degC. Water properties are as follows: density=995kg/m3, kinematic viscosity=.657x10-6 m2/s, Pr=4.43, k=.628W/mK, cp=4178J/kgK. a) Determine the Reynolds number b) What is the thermal coefficient on question number c) what is the heat absorbed by the water?
