Problem 2: Heat Exchanger

Consider that you are a heta specialist studying water boiling phenomena (two phase: liquid and vapor) under a forced convection U in a heat exchanger with rod bundles as shown. The rod is kept at a temperature tex2html_wrap_inline159 and water inlet at temperature at tex2html_wrap_inline161 , inlet pressure at tex2html_wrap_inline163 . You are asked by your boss to make a dimensional analysis of the problem including all variables relevant to the problem and to come up with a set of dimensionless parameters relating heat transfer pramater (Nu) to other parameters (flow, geometry, properties)
