T, = Initial temperature of solution in F. T2 = Final temperature of solution in F. Length of pipe required = VX Wx (T2--TJ XSpX 12 HXMXDX 3.1416 where V = Volume of solution in gallons W = Weight of solution in lbs. per gal. T2 = Temperature to which solution is to be heated in F. T, = Initial temperature of solution in F. Sp = Specific heat of solution. H = Heat transfer in B.t.u./sq. ft./F./hr. Varies from 50 to 150. See note below. M = Mean temperature difference F. D -- Outside diameter of lead pipe in inches NOTE: H varies with the outside film conductivity of solution, the inside film conductivity of heating medium, the lead pipe wail thickness, the agitation outside the coil, and the speed of flow inside the coil. For a thorough consideration of heat transfer problems, consult engineer ing books on the subject. NLI 115286 27 ff 44 j| , i. ! ;1; ,s > 'ii* ^ I ' ; ` i i { j i { *< ?
