How many kw in 80000 btu?

Answer 1

It takes 970 B.T.U.s to change one pound of water to steam at any temperature. When water evaporates from your skin, from a glass or swimming pool at room temperature it takes with it 970 B.T.U.s per pound of water. It is not necessary for water to be heated to 212F to evaporate. Whenever water evaporates (turns into a gas) it takes with it 970 B.T.U.s per pound. If you want to boil water, it takes one B.T.U. for each degree F you raise the temperature of water till you get to 212F. At 212F, at sea level, water will not get hotter than 212F until every last bit of it has turned into a gas.

The heat to transform liquid water to gas water is called the heat of vaporization, or the latent heat of evaporation. The heat to liquify water is called the heat of crystalization.

Because the water's heat of vaporization is so high, water has cooling power. Outdoor misters are based on this principle. They spray a super fine mist of water into the air. Because the water in this super fine mist has a very large surface area, it evaporates at normal ambient tempemeratures. Air is hydroscopic. That means air naturally absorbs water. The less water or humidity there is in the air, the faster this process takes place.

Whenever matter changes state from solid to liquid or liquid to gas, it takes heat to break the chemical bonds.

Answer 2

BTU, or British Thermal Unit, is an amount of energy. kW, or kiloWatt, is an amount of power, which is a measure of how fast energy is used or produced, similar to horsepower.

Converting BTU to kW is like converting miles per hour to feet: they are not the same type of unit.

That said, 80,000 BTU is equal to 23.44 kWh, or kiloWatt hours.

At 1000 watts, or about ten light blubs, it would take 23.4 hours to use 80,000 BTU of energy.

A typical car using 100 horsepower would take about 20 minutes to burn 80,000 BTU worth of gasoline.

Answer 3

This is an apples and Oranges comparison, so it cannot be made. (No matter how many apples you have, you have no oranges, and vice verse.) 10 kw is an energy flow rate. Every second 10,000 watts are {created | used | whatever}. A BTU {British Thermal Unit} is a fixed amount of energy. Not every second: ONCE. That said, 10 KW for 1 second is equivalent to 9.48 BTU. Or, said another way, 10 KW continuous is the same as 9.48 BTU per second; another 9.48 each and every second.

Power and energy are tricky. Energy is a fixed amount. Power is energy per unit time. Power is a flow. Think of the car. The 250 horsepower from the engine (wish on) is continuous. As long as there is gas in the tank, the power will flow. Same with 10 kilowatts. Pay the bill and the light stays on.

Answer 4

80,000 BTU/hr is 23.446 (23.445683093) kW
