How many btus are needed to heat one lb of water one hundred degrees?
100 BTU if it's Fahrenheit
How many btus to raise 1 pound of water from room temp deg to steam 213 deg?
First convert 1 lb of water to lb-moles which is 0.055 lb-moles (you'll need this later). This problem can be broken into 3 steps:(1) You need to detemine how much heat is needed to raise room temperature water (68oF) to 212oF. This can be used using the heat capacity of water which at room temperature is 1 Btu/lboF. So the amount of heat needed for this is:Q1 = m*Cp*ΔT= (1 lb)*(1 Btu/lboF)*(212 - 68oF)= 144 Btu(2) Next you need to account for the phase change. The water changes to steam at 212oF. You use the heat of vaporization which you can look up in any Chemistry or Chemical Engineering Handbook. The Hvap that I found is 17493.5 Btu/lb-mole.Q2 = n(lb-moles)*Hvap= (0.055 lb-moles)*(17493.5 Btu/lb-mole)= 972.64 Btu(3) Next you need to find out how much heat is needed to raise the temperature of the steam from 212 to 213oF. You can look up the heat capacity of steam at 212oF to be 0.485 Btu/lboF.Q3 = m*Cp*ΔT= (1 lb)*(0.485 Btu/lboF)*(213-212oF)= 0.485 BtuTo find the total heat needed add Q1+Q2+Q3 (144+972.64+0.485) =1117.12 Btu
How many BTU per Hour equals 1 kilowatt?
1kW is 3,412.13 BTU/hr
How many Btus are required to change one pound of water at 40F to 200F?
160 btu's. It takes 1 btu (British Thermal Unit) to change the temperature of 1lb of water 1°. This is referred to as sensible heat. This 1 to 1 ratio does not hold true when changing the state of that water to ice or to steam. Changing the state 1lb of water at 212° to 1lb of steam at 212° you must add 970 btu's and to change 1lb of water at 32° into 1lb of ice at 32° you must add 144 btu's. This is referred to as latent heat.
How many btu's we add to one 15 pounds of water at 212 Fahrenheit to make steam at 212 Fahrenheit?
The latent heat of vaporization of water at 212 degrees Fahrenheit at atmospheric pressure involving only vaporization and no saturation is 970 BTU/lb, so to evaporate 15 lbs of water we need 970 x 15 = 14550 BTU's
How many BTU to heat a 2000 sq ft house?
I cannot really answer that depends on your insulation of walls heat leaks windows and so forth. NOT TO MENTION EFFICIENCY OF HEATING.
How many BTU to heat a 1400 sq ft house?
60000
How many square feet does a 40000 btu heater heat?
Will a 40,000 btu furnace be enough to heat my 1375 square foot middle unit town house.
How many btu's to heat 2400 square feet?
approx 80,000 if your house has average insulation and heat loss.
How many square feet does a 8000 btu heater heat?
The number of square feet that an 8000 btu heater will heat can not be accurately determined just by knowing the output of the heater.Given a small, well insulated, energy efficient house that is located in a mild climate, 8000 btu could be sufficient to heat the entire house.
How many btu does it take to heat a house of 2180 sq ft?
2180 SqFt/500 = 4.4 tons of AC required x12000 BTU/ton = 52800 BTU's Answer is it takes 52800 BTU's to cool a 2180 SqFt home
How many square feet does 14000 BTU heater heat?
how many square feet does a 14,000 btu heater heat
