resistance developed at a speed of 16 knots after. various periods is shown in Figure 2 as a per cent. of the initial resistance of the freshly painted hulL. In 375 days the total resistance is exactly doubled.
chilling - the process of becoming cooler; a falling temperature. cooling, temperature reduction. freeze, freezing - the withdrawal of heat to change something from a liquid to a solid. heat dissipation - dissipation of heat.
A temperature of one degree below the base temperature for one hour causes one Chill Hour to accumulate. If the temperature is 4 degrees below the base temperature for one hour then 4 Chill Hours accumulates and so on. One extra wrinkle is that below 0ÂºC chilling is ineffective so chilling is taken as zero for temperatures below 0ÂºC.
