Atwood’s are the standard 13,500 BTU Air Command and 15,000 BTU AC with a heat pump. Installation and Maintenance If you’re purchasing a new RV camper air conditioner, you’ll likely need to install it yourself, which is a relatively straightforward task since manufacturers will provide instructions on how to do so.

Assume the water is initially at 40 F and 14.7 psia.
m = ( 1.0 gal ) ( 1.0 ft^3 /7.4805 gal ) ( 62.43 lbm / ft^3 ) =8.346 lbm
Q = Delta U = ( m ) ( Cv ) ( T2 - T1 )
Q = ( 8.346 lbm ) ( 1.00 Btu / lbm - Fdeg ) ( 200 F - 40 F ) = 1335Btu <----------------
m = ( 1.0 gal ) ( 1.0 ft^3 /7.4805 gal ) ( 62.43 lbm / ft^3 ) =8.346 lbm
Q = Delta U = ( m ) ( Cv ) ( T2 - T1 )
Q = ( 8.346 lbm ) ( 1.00 Btu / lbm - Fdeg ) ( 200 F - 40 F ) = 1335Btu <----------------

How many BTUs does it take to heat 390 gallon tank of water from 60 degrees to 248 degrees?
The specific heat of water is 1 BTU per pound per degree Fahrenheit. There are 8.3378 lbs/gallon at 60 degrees, which equals 3251.742 pounds of water. The number of BTUs to raise it 188 degrees is then 611,327.496 BTUs. Read More
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. Read More

How many btu in 60 gallon water in storage tank?
89,964 Btu's in 60 Gallons of water. Here's the formula. Gallons times maximum temperature rise times weight of one gallon equals Btus. In the example, Gallons = 60 Max temp rise = 180째F or from freezing to boiling, 212째F minus 32째F weight of one gallon = 8.33 lb 60 x 180 x 8.33 = 89,964 Read More
What changes water from a solid to a liquid to a gas?
Heat. Ice, solid water, at 32 degrees F needs 144 btus of heat per pound to liquify completely. Water at 212F needs 970.3 btus per pound to evaporate completely into dry steam. Water vapor (visible steam), in air, {say from a pot} is actually about 3 to 10% dry steam and only required about 28 to 100 btus per pound to vaporize and become airborne, This is an odd characteristic of water, that varying proportions… Read More
How many mcf of natural gas equals the btu of 1 barrel of crude oil?
A fourty two (42) gallon barrel of oil generates approximately 5,600,000 btus. A cubit foor of nat gas generates 1,200 btus ,there for you would need 4,666.67 cubic feet of gas or 4.6 mcf. Today, an mcf of nat gas costs $2.6 an mcf, a barrel of oil $106. The btu per dollar breakdown looks like this. 5,600,000 btus = 1 barrel of crude oil = $106 5.6m btu / $106 = 52,830 btus per… Read More
How many btu are in a gallon of propane?
Type your answer here... there are around 91,600 BTUs in a gallon of propane. The standard BBQ sized bottle of propane contains 11 pounds of propane. Propane weighs about 4.2 pounds per gallon, so that 11 pounds of propane is about 2.5 gallons in its liquid state. That means there is 91,600 BTUs/Gal times 2.5 gallons so a BBQ sized tank of propane contains about 2.3 million BTUs. If your BBQ has a 50,000 BTU… Read More

What is the tonnage of a 108000 btu ac?
A ton of refrigeration is defined as the amount of heat removal required to change one ton of water (2000 pounds) at 32 degrees F to one ton of ice at 32 degrees F in one day which is 288000 BTUs. Today it is assumed that BTU ratings are by the hour, so one ton of refrigeration is the removal of 1200 BTU/hr. So if your air conditioning unit is removing 108000 BTUs/hr it is… Read More
How many btus are required to change 5 pounds of ice at 32 degrees to steam at 82 degrees?
The question cannot be answered because: the temperature scale being used has not been specified, There is no normal temperature scale in which you can have ice at 32 degrees and steam at 82 degrees without large changes in pressure. If changes in pressure are permitted then there is no simple formula to calculate the amount of heat (btus) required. Read More

How many btu's in office water-cooler?
There are no BTUs in an office water-cooler. But you can calculate how many BTUs are removed by the cooler. One BTU or British Thermal Unit is the amount of heat energy required to raise the temperature of one pound of water one degree Fahrenheit. There for when you remove one BTU you are lowering one pound of water one degree Fahrenheit. So if you know how many pounds of water you have and the… Read More
How many BTUs does it take to heat a 1250 gallon pool of water from 50 degrees to 82 degrees?
{Sigh} I hate English units. A BTU is defined as the amount of heat required to raise the temperature of 1 lb of water by 1 deg F. The basic relation is Q = mcdT Heat = mass * heat capacity * change in temperature. A gallon of water weighs about 8 lb, so you're talking about 500,000 gal * 8 lb/gal = 4 million pounds. The constant c for water, by the definition given… Read More
Look at the efficiency rating. While furnaces are rated by their effectiveness in delivering the heat they generate, air conditioners are rated by how efficiently they use electricity over the course of a typical operating year. One such rating is the Seasonal Energy Efficiency Ratio (SEER) rating, created by the Air Conditioning, Heating, and Refrigeration Institute, which is the ratio of the unit's cooling output in BTUs divided by the energy in watt-hours needed to run it for the entire operating year. (Note that 1 kilowatt-hour equals 1,000 watt hours.)[7]- For example, take a 4,000 BTU/hour air conditioner run for 1,000 hours during an operating year using 400,000 watt-hours of electric power. This air conditioner would have a SEER rating of 10, since 4,000 x 1,000 / 400,000 = 10.
- To find the average power consumption divide the unit's power in BTUs per hour by the SEER rating. Since the SEER rating is in units of BTU per Watt-hour, your answer will be in terms of watts. In the example above, (4,000 BTU/h) / (10 BTU/Wh) = 400 W.
- To find the cost per hour of operation, multiply the average power consumption in kilowatts by the cost of your electricity per kilowatt-hour. In our example, the unit's consumption is (400 W) / (1,000 W/kW) = 0.4kW. If your electricity costs 5 cents per kWh, this unit costs 0.4kW x 5 ¢/kWh = 2 ¢/h (cents per hour).
- Central air conditioners manufactured in the United States since January 2006 are required to have a SEER rating of at least 13, or 14 to be Energy Star qualified. Room air conditioners are currently exempt from this requirement; many have SEER ratings closer to 10.
