Increasing the total flow of fresh cooling water to a heat exchanger is not always possible or desirable (see 11.2) but even with a fixed quantity the designer has several options:11.1.1 Tube side water flow Options include:(a) Increase the length and reduce the number of tubes. This may not be possible as it may raise the shell side pressure
Jul 23, 2012 · Jul 23, 2012. Usually associated with long distance passagemaking, keel cooling remains a viable alternative for reliable diesel engine operation. Rather than pumping raw water into your boat to cool down the engine through a heat exchanger, as is the common practice on many cruising powerboats, a keel cooler works much like the radiator in Chapter 16 HEAT EXCHANGERSpipe heat exchanger can not be in the order of 700. Therefore, it can not be classified as a compact heat exchanger. 16-4C In counter-flow heat exchangers, the hot and the cold fluids move parallel to each other but both enter the heat exchanger at opposite ends and flow in opposite direction. In cross-flow heat exchangers, the
