To use log-log slide rule for cooling calculations set any cooling time on the B scale beneath the corresponding fraction of initial temperature difference on LLOO scale. All other cooling times and fractions of initial temperature difference will then correspond. Setting shown is for seven-eighths cooling in 3 hours or one-half cooling in 1 hour. <•- I—75 T3 u_ t_ 0 o uj 60 o or *• z> a; »- o i/2- [ Air temperature I ^^^^ / /-—\ 1 -^^^r^^^ 15/16 Cool 1 -l -i =- i n i i i i i i 3 6 9 12 HOURS OF COOLING Fig. 37.
