data for levulose in water

e=100(c'—c.)/cı, in which e' stands for the weight of levulose dissolved in unit weight of water in the erature, t, according to the equation c-0.1501032-0.814t+331.023, as listed in table 138. The index of levulose contents per unit weight of water, regardless of existing temperature, expressed as a percentage for the specified temperature of 20° C; in the last column, headed "yo", (hypothetical yield at 20°), this temperature, instead of as a percentage of the weight which would exactly saturate the water at 20° C. In practical application only the first three or four digits should be used]
