Pressure Drop Calculation for Rectangular Channels

There are many examples of flow in rectangular channels in the cooling world. You have your basic heat exchangers, heat sinks (a misnomer if there ever was one - really they are heat exchangers too), stacks of two or more circuit boards, convection belt furnaces, even your car radiator. The analysis that follows might underestimate the pressure drop for circuit boards - they tend to be kind of rough topologically.

SF Pressure Drop 6.0 for Windows
calculates pressure drops of flowing liquids and gases in pipes (laminar and turbulent flow). Additional it's possible to calculate pressure changes caused by vertical difference of pipe and caused by changes of kinetic energy.
