Heat Transfer problem:


7. Water at its saturation point at atmospheric pressure is heated in a small cylindrical copper tank that has a diameter of 15 cm. The bottom surface of the tank is kept at 115 °C A. what rate of energy addition to the bottom of the pan is needed to boil the water and maintain 115 °C? (w) B. What is the rate of evaporation of water from the pan? C. What fraction of the maximum heat flux for nucleate boiling is used at this surface temperature?

******Hint: You need to assume that the copper is either scored or polished to solve this problem.*******

Experiment2: Determination of Alcohol content of Wine by Fractional Distillation Introduction If a mixture of ethanol and water are warmed you might expect the more volatile (lower boiling) ethanol to boil first and then the water. This is not exactly true. As the mixture is warmed all the molecules within the flask will gain energy. In fact...
