+** Details: 
+** A zero capacitance sensible heat exchanger is modeled in various configurations. In this instance, a counter flow
+** heat exchanger is modeled. Given the hot and cold side inlet temperatures and flow rates, the effectiveness is
+** calculated for a given fixed value of the overall heat transfer coefficient.
