Calculate how many BTUs you need to heat a room or even a house with a wood-burning, pellet or gas fireplace, insert or stove. This BTU Calculator...
The British thermal unit (Btu) is the heat needed to raise the temperature of a pound of water by a Fahrenheit degree. Other substances, however, absorb heat at different rates, with each having their own specific heat capacity. You can use Btus to calculate their heat requirements as well...
How To Calculate CFM For A Room? (Solved Example) Let’s say we have a big 1,000 sq ft room with standard 8 ft high ceiling. We want to calculate the CFM of a fan that will exchange all the air in such a room every 15 minutes (ACH = 4). ...
I have an open drum filled with water, 100lt and heating with a LP gas burner. How do I calculate the BTU hr heating the water to say 100 C I need a safety tilting valve to cut off the gas flow...
How to Calculate Room CFM – An Example You can check this example with the CFM Calculator above. Try various inputs to see how the data changes as you change room size and necessary ACH – air changes per hour. Room size:400 square feet with 10-foot ceilings, or 4,000 cubic feet ...
An air conditioner's BTU (for British Thermal Unit) rating is a measure of its cooling power. An 8,000 BTU window unit, for instance, can typically cool a room of 300 to 350 square feet, according to the California Energy Commission. However, window AC units with the same BTU rating ...
A range hood should be large enough to ventilate the air in your kitchen. If your kitchen design is relatively small, then a range hood of a lower CFM would work fine in removing strong odors. You can calculate how many cubic feet per minute (CFM) of air your range hood needs by mult...
According to The U.S. Department Of Energy recommendation for the size of room air conditioners: “…an air conditioner generally needs 20 BTU for each square foot of living space.” Based on room size, ceiling height, and other conditions, you can calculate how many BTU air conditioner you...
Windows.If your data facility has windows, you must calculate how much heat is generated by sunlight from all windows. A general calculation is 60 Btu/hour/ft2of window. ASHRAE considers location, hours of sunlight, building materials, window materials, refraction rates and more in their calcula...
Determine the starting wattage (energy needed to turn it on) and running wattage (energy needed to operate it) for each piece of equipment. These figures are typically inscribed somewhere on the equipment itself, as well as recorded in the owner’s manual. Calculate your total power requirement...
