C30A is the series of the evap coil. The nominal BTU rating (cooling) for this coil would be 48,000 BTUH (signified by the -047). The "U" indicates upflow, although it can be used in downflow orientation, as well. The "B" would be the case size - 17 1/2" wide.
21000
The 030 in the Model number refers to the BTU Rating. So it is a 30,000 BTU unit. There are 12,000 BTU per ton so that is a 2 1/2 Ton Condenser.
I don't know if anyone answered your question of not but that unit is 24,000 BTU
For the purpose of gas rating 1040 btu's/ft3
100,000 btu input. The output depends on the efficienct rating of the furnace, ie 95%efficient = 95,000 btu output, 80% = 80,000 btu output.
Oil has the higher BTU rating Depends. If it is Liquified Nat. Gas then it has the higher rating.
Heptane has the chemical formula of C7H16. It has a BTU rating of 19,163 BTU per pound and a rating of 4,465.8 kilojoules per mole.
12.5 tons
138,700 btu's
Divide the btu output rating by the btu input rating. Both of these values can be found on the furnace`s nametag.
the golden birch has the highest btu rating followed by hard maple for trees found in eastern us/canada Actually the osage orange tree has the highest btu rating of any wood in the united states.
Gasoline has a btu rating of around 110,000. Ethanol has a btu rating of around 76,000.
