16-3C A heat exchanger is classified as being compact if > 700 m2/m3 or (200 ft2/ft3) where is the ratio of the heat transfer surface area to its volume which is called the area density. The area density for double-pipe heat exchanger can not be in the order of 700. Therefore, it can not be classified as a compact heat exchanger. Consider Open-Rack Seawater Heat Exchangers Chemical

and calculated, given the heat-exchanger effectiveness , the mass-flow rates and specific heats of the two fluids and the inlet temperatures.. The value of depends on the heat-exchanger geometry and flow pattern (parallel flow, counterflow, cross flow, etc.).
