It doesn't work that way. There is not a certain number of btus to raise air temperature. You would have to know how much air.
A BTU is the British Thermal Unit. That is the amount of energy required to raise the temperature of one pound of water one degree F.
U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.
A US gallon of water is about 8.4 lb, so 30,000 galls is 252,000 lb. One BTU is the heat to raise one pound of water by one degF, so BTU's in your example are 252,000 x 15 = 3,780,000 BTU.
0.104 btu
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
That would depend on the size of the room and the humidity.

It takes 8.33 BTU to raise the temperature of water 1 degree F.
U.S.gallon = 8.33 pounds of water. Therefore to raise the temperature by one degree F will require 8.33 BTU. The initial temperature of 50 F is inconsequential.
If measuring heat, a BTU measures the amount of heat that is required to raise the temperature of a pound of water to 1º Fahrenheit. In terms of air conditioning, the BTU determines the amount of heat the unit can remove from the room. As the BTU rating increases, so does the size, weight and cost of the unit.
A US gallon of water is about 8.4 lb, so 30,000 galls is 252,000 lb. One BTU is the heat to raise one pound of water by one degF, so BTU's in your example are 252,000 x 15 = 3,780,000 BTU.
7,803,495 BTU's Assuming it's water that's being heated and the temperature is Fahrenheit: 500*250*62.42796 (<the weight of one cubic foot of water)= 7,803,495 BTU's
This question can not be answered without know much more information. Such as the material that needs to have its temperature changed. How much of that material there is.

A BTU is the amount of heat required to raise the temperature of 1 pound (0.454 kg) of liquid water by 1 °F (0.56 °C)therefore = to about 1055 joules.
A British Thermal Unit (BTU) is the amount of heat energy needed to raise the temperature of one pound of water by one degree F. 1 Gallon of Propane is 91,600 BTU's.
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
BTU's or British Thermal Units are used to decide the amount of air that can be altered in a set time limit. The larger the air mass you need to change temperature of in a set time determines the BTU rating of the apliance you need. The more cubic area you have the greater BTU rating will be. Actually 1 BTU is equal to the energy required to raise 1 pound of water from 60 degrees to 61 degrees in one hour
