A hash function maps keys to small integers (buckets). An ideal hash function maps the keys to the integers in a random-like manner, so that bucket values are evenly distributed even if there are regularities in the input data. This process can be divided into two steps:1  Map the key to an integer. hash function maps keys to small integers (buckets).

Electrical energy consumption were measured as 0.001 kWh for 5 C, 4 C, and 3 oC and 0.003 kWh for 2 C, 0.006 kWh for 1 C, 0.001 kWh for -1oC, 0.109 kWh for -2oC and 0.120 kWh for -3 C. Mean. energy consumption of the compressor was 0.035 kWh/ oC for positive cold storage temperatures (from 5 C to 0oC) and 0.093.
5 to 7.2 Cubic Feet. The smallest deep freezers offer 5 to 7.2 cubic feet of capacity. Energy Star models use 230 to 282 kilowatt hours of electricity each year, which translates to an annual operating cost of $24 to $30.You'll need 294 to 362 kilowatt hours of electricity to operate a chest freezer with 8.8 to 12.8 cubic feet of capacity.Expect to spend $31 to $39 to run these models for a 12-month period. Energy-Star models with 13 to 14.9 cubic feet have an annual energy use of 326 to 397 kilowatt hours.nergy Star models use 230 to 282 kilowatt hours of electricity each year, which translates to an annual operating cost of $24 to $30.
