How many BTUs will it take to change 1 gallon of water at 32 degrees to ice at 32 degrees?
You would need to remove approximately 1200 BTUs of heat to convert a gallon of water to ice. There are 8.34 lb in a gallon of water, which converting to lb-moles is 0.463. The latent heat of crystallization for water is -2583.4 BTU/lb-mole. Multiplying the two together and you get -1197 BTUs, which means you need to remove that amount of heat to convert the gallon of water to ice.
How many pavers would you need to cover a 60 sq meter area?
3600
How fast is 89.44 miles per second in miles per hour?
Since an hour has 3600 seconds, you need to multiply the miles per second by 3600.
How many milliseconds is 3600 seconds?
There are 1,000 milliseconds in a second. Therefore to convert from seconds into milliseconds you need to multiply by 1,000. In this case we have 3600 seconds, so multiply by that by 1,000: 3,600 x 1,000 = 3,600,000 Thus there are 3,600,000 milliseconds in 3,600 seconds.
Convert CFH to BTU?
To convert CFH to BTU, you need to use the formula 1 CFH which is equivalent to 1000 BTUs.
How many BTUs do I need to cool a 20x9 room?
A romm 20x9 is 180 square feet. You will need 5000 to 6000 BTUs for this.
How many btu's does it take to heat a basement room 150 square feet?
Standard practice holds that it takes 5000 BTUs to heat a room 100 to 150 sq ft Figure on adding another 1000 BTUs for every 50 or so sq ft added. Hence , 400 to 450 sq ft would need about 10,000 BTUs
How can I determine how many BTUs I need for an air conditioner?
A small room is about 5,000 BTUs. Most people don't have a room that would require more than 10,000 BTUs.
How many watts in 12000 BTU?
To convert a watt to BTUs, the factor is 1 kilowatt of power = 3412.1416 BTU/hr 3.412 BTUs equal a watt. 1200 watt = 4094.4 BTUS you will need to remove about 4100 BTU/hr
What sort of research should I do when in the market for an industrial heater?
Know the number of BTUs recomended for the size area you need to heat. Know the safety specifications.
How many cfms do you need for 15000 btus gas range?
uhhh, you got any gum
How do I determine how many BTUs I need per foot for each room when purchasing portable heaters?
It depends on the climate and how well your home is insulated.A good rule of thumb is about 20 BTUs per square foot.

How many square feet will 140000 btu's heat?
It doesn't work that way. BTU is a unit of energy, not a unit of power. In other words, to heat a certain building you would need a certain amount of BTU per hour, a certain number of BTUs per second, or some other unit of power.
What size return air grill for a 48000 BTU heating system?
48,000 btus is equal to 4 tons of air flow, 12,000 btus per ton. You need 144 sq in per ton. Return grill should be 24x24. 48,000 btus is equal to 4 tons of air flow, 12,000 btus per ton. You need 144 sq in per ton. Return grill should be 24x24. 48,000 btus is equal to 4 tons of air flow, 12,000 btus per ton. You need 144 sq in per ton. Return grill should be 24x24.
Air conditioner tonnage calculation?
Calculating the appropriate tonnage (cooling capacity) for an air conditioner is essential to ensure that the unit effectively cools the desired space. The tonnage required depends on factors such as the room's size, insulation, climate, and heat-generating sources. The British Thermal Units (BTUs) are commonly used to measure cooling capacity. Here's a general guideline for calculating the required tonnage: 1.Determine the Room's Square Footage: Measure the length and width of the room in feet, then multiply these dimensions to get the square footage. For example, a room that is 20 feet long and 15 feet wide has a square footage of 20 x 15 = 300 square feet. 2. Consider the Insulation: If the room is well-insulated, you can use the following BTU formula: BTUs = Square footage x 25 3. Adjust for Insulation and Climate: If the room has poor insulation or is in a particularly hot climate region, you may need to adjust the BTU calculation. Here's a more detailed formula: BTUs = (Square footage x 25) + (Extra BTUs for insulation and climate) The "Extra BTUs for insulation and climate" factor depends on the insulation quality and climate conditions: Well-insulated room: No extra BTUs needed (0) Average insulation: Add 10% to the calculated BTUs Poor insulation: Add 20% to the calculated BTUs Hot climate (sunny and above 90°F): Add 10% to the calculated BTUs Very hot climate (sunny and above 100°F): Add 20% to the calculated BTUs 4. Account for Heat-Generating Sources: If the room has significant heat sources (such as large windows, many occupants, or heat-generating appliances), you may need to add extra BTUs to compensate for this heat load. The exact adjustment depends on the specific heat sources present in the room. 5. Convert BTUs to Tons: Air conditioner capacity is typically measured in tons. To convert BTUs to tons, divide the calculated BTUs by 12,000 (1 ton = 12,000 BTUs). For example, if the calculated BTUs are 24,000, the required tonnage is 24,000 / 12,000 = 2 tons. It's essential to use these calculations as a starting point and consult with a professional HVAC technician to ensure that the air conditioner is correctly sized for your specific needs. Factors such as the number of occupants, local climate, and unique room characteristics can influence the tonnage requirement. Oversized or undersized air conditioners can lead to inefficiency, discomfort, and higher energy bills.
