I had the same question and the only answer I could find was this: To raise the temperature of 1 LB of water from 40 ºF to 41 ºF would take 1 BTU To raise the temperature of 1 LB of water from 177 ºF to 178 ºF would also take 1 BTU However, if you tried raising the temperature of water from 212 ºF to 213 ºF you would not be able to do it. Water boils at 212 ºF and would prefer to change into a gas rather than let you get it any hotter. Something of utmost importance occurs at the boiling point of a substance. If you did a little experiment and added 1 BTU of heat at a time to 1 LB of water, you would notice that the water temperature would increase by 1 degree Fahrenheit each time. That is until you reached 212 ºF Then something changes. You would keep adding BTU's, but the water would not get any hotter! It would change state into a gas and it would take 970 BTU's to vapourize that entire pound of water. This is called the Latent Heat of Vapourization and in the case of water it is 970 BTU's per pound.

What does MBh mean in air conditioning terms?
MBh stands for One Thousand BTU per hour. BTU stands for British Thermal Unit. MBh units should help with the cost estimate of running your air conditioning (AC). It's a measure of the heating/cooling capacity of AC equipment.MBH - One MBH is equivalent to 1,000 BTU's per hour. The 'M' is derived from the Roman Numeral M that equals 1000. Such as MMIX = 2009.(This M is often confused with the SI (Système International) 'M' which stands for the prefix Mega, equal to One Million (1,000,000). Note BTUs and therefore MBH are Imperial Units.)BTU - A standard unit of measurement used to denote both the amount of heat energy in fuels and the ability of appliances and air conditioning systems to produce heating or cooling. It is is the amount of heat required to increase the temperature of a pint of water by one degree Fahrenheit. BTUs are measurements of energy consumption, and can be converted directly to kilowatt-hours (3412 BTUs = 1 kWh) or joules (1 BTU = 1,055.06 joules). A wooden match produce approximately 1 BTU.
What is the HEIL airconditioner model number nxh530gka100 tonnage?
2.5 tons. Whenever you see multiple digits digits together in a model #, any brand, the last 2 digits in the FIRST series of numbers is the btu output. So in this case you take the 30 out of nxh530gka100 and you have 30. ! ton of cooling is equal to 12,000 btus so 30 is 30,000 btus divided by 12,000 equals 2.5 Any questiions about HVAC contact John at shojohn@yahoo.com
What does MBH input mean in gas heating boilers?
MBH [ thousands of BTUs per hour] is an expression for the rate of energy consumption or production: M is for thousands, B is for Btu's (Brittish Thermal Units) and H is "per hour" . ie: 860,000 Btu's per hour = 860 MBH
How many BTUs are required to raise the temperature of 15 pounds of water from 100F to 120F?
To calculate the BTUs required to raise the temperature of water, you can use the formula: BTUs = (pounds of water) x (temperature change in °F) x (1 BTU). For 15 pounds of water going from 100°F to 120°F, the calculation would be: BTUs = 15 pounds x 20°F x 1 BTU = 300 BTUs.
How many BTU are generated to get water to 212 degrees?
To bring water from room temperature (around 70 degrees Fahrenheit) to boiling (212 degrees Fahrenheit), you need to add approximately 180 BTUs per pound of water. This is known as the heat of vaporization, which is the amount of energy required to change water from liquid to gas at its boiling point.
How many BTU will it take to change 10 pounds of ice at 20 degrees to steam at 220 degrees?
To change 10 pounds of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit, you need to supply enough energy to first melt the ice, then heat the water to the boiling point, and finally convert it to steam. This process requires approximately 180 BTUs per pound of ice to melt it, 180 BTUs per pound of water to heat it to the boiling point, and then 970 BTUs per pound of water to convert it to steam. So, for 10 pounds of ice, the total BTUs required would be around 18,300 BTUs.
How many BTU's does it take to evaporate one pound of water?
BTUs to Evaporate One Pound of WaterQuick Answer: Somewhere around 1000BTU/lb Long answer: It depends on the temperature of the water you start with. Before you can evaporate the water, you must heat it to it's boiling point. The warmer the water you start with the fewer BTUs will be needed to heat the water to its boiling point. Keep in mind the BTUs require to raise the water to its boiling point are very few compared to the BTUs required to change the water from a liquid to a gas.One pound of steam contains 1150 BTUs. This is the energy you need to put into the water for it to evaporate if you start with water at 32F. If you start with water at 100F the water already has 70 BTU/lb so the BTUs required to evaporate the water when you start at 100F is 1150-70 = 1080 BTU and so on.You can get all this information in a steam table which can be found easily by searching the web.
How many btus are required to raise the temperature of 15 pounds of water from 100 degrees fahrenheit to 130 degrees fahrenheit?
To calculate the BTUs required to raise the temperature of 15 pounds of water, you can use the formula: BTUs = Weight of water in pounds × Temperature change in degrees Fahrenheit × 1 BTU So, the calculation would be: BTUs = 15 lbs × (130°F - 100°F) × 1 BTU = 15 lbs × 30°F = 450 BTUs.
How much heat is required to vapourize 5 pounds of water?
It takes approximately 970 BTUs to vaporize one pound of water. Therefore, for 5 pounds of water, it would require 4850 BTUs to vaporize all of it.
How many btus are required to change one pound of ice at 20 f to steam at 220 f?
It takes approximately 144 BTUs to change one pound of ice at 20°F to water at 212°F, and an additional 970 BTUs to change the water to steam at 220°F, for a total of 1114 BTUs.
How many Btu's are required to change one pound of ice at 20 F to steam at 220 F?
To change one pound of ice at 20°F to steam at 220°F, you need to consider two processes: heating the ice to 32°F, melting the ice at 32°F, heating the water to 212°F, and finally boiling the water to steam at 220°F. The total number of BTUs required for this process is around 1440 BTUs.
How many btus are required to change five pounds of ice at 20 degrees to steam at 220 degrees?
6,520 Btus
How many btus are required to change 5 pound of ice at 20 degrees Fahrenheit to steam at 220 degrees Fahrenheit?
To change 5 pounds of ice at 20°F to steam at 220°F, you will need to go through multiple phases: raise ice temperature to 32°F, melt ice to water at 32°F, raise water temperature to 212°F, and then convert water to steam at 212°F to steam at 220°F. The total heat required, in BTUs, is around 503 BTUs per pound of ice, which translates to about 2515 BTUs for 5 pounds of ice.
What is the BTU formula?
BTUs, or British Thermal Units, measure the amount of heat energy required to raise the temperature of one pound of water by one degree Fahrenheit. The formula to calculate BTUs is: BTUs = weight of water (in pounds) x temperature change (in degrees Fahrenheit) x 1. Alternatively, the formula can be expressed as: BTUs = (Flow rate in gallons per minute x change in temperature in degrees Fahrenheit) / 500.
