(7-24) H = total heat transfer rate, BTU/hr. For heat.
exchangers, Ref [33a] recommends that this
value be taken as the maximum exchanger duty
where GPM = flow rate at the flowing temperature, gal/min during operation.
13 = cubical expansion coefficient per degree F for G = specific gravity referred LO water. Ignore fluid
the liquid at the expected temperature. For val- compressibility.
ues see specific liquid data or see table below
for typical values. Ch = specific heat of the trapped fluid, BTU/lb/°F
