How much water is lost when boiling a kettle?

A big piece of the energy loss is due to evaporation. By boiling each cup individually, I lost 52 grams of water (between 12 and 15 per cup) due to evaporation. Those steam molecules take energy with them to the tune of 2257 joules per gram (the heat of vaporization).

How much water boils off in an hour?

Water is usually boiled off at a rate of about 4% per hour.

How do you calculate boil off rate?

Measure the volume both at the beginning and end of the boil and calculate the difference. Divide by the boiling time in hours to determine the evaporation rate.

What is the average boil off rate?

The amount of liquid that is evaporating from a cargo due to heat leakage and expressed in % of total liquid volume per unit time. Typical values are 0.15%/day and below, recent projected LNG carriers are offered with a BOR close to 0.1%.
