#2 fuel oil = 140,000 btu/gallon. Psi does not matter.
Oil has the higher BTU rating Depends. If it is Liquified Nat. Gas then it has the higher rating.
A simple-cycle gas turbine used for power generation has a thermal efficiency of about 34 percent. Since 1 kwh is theoretically equivalent to 3,415 Btu, the simple-cycle gas turbine has a fuel connsumption of: 3,415 / 0.34 = about 10,000 Btu/kwh. Given the heating value (i.e, heat of combustion) of a fuel, we can easily calculate the simple-cycle gas turbine fuel usage. For example, natural gas has a net heating value of about 21,500 Btu/pound. Thus, the natural gas consumption in a simple-cycle gas turbine would be: 10,000 / 21,500 = 0.47 pounds/kwh = 0.21 kg/kwh. As another example, a typical diesel oil has a net heating value of 130,000 Btu/gallon. Thus, the diesel oil consumption in a simple-cycle gas turbine would be: 10,000 / 130,000 = 0.077 gallon/kwh. (The gallon used just above is the U.S. gallon rather than the Imperial gallon) A combined-cycle gas turbine will have a higher thermal efficiency and, hence, lower fuel consumptions.
You do not mention how much you want to heat the water and in what period of time. But here are the figures: 1 btu = temperature increase of 1* F of 1 pound of water. One gallon of water weighs 8.33 lbs. So a boiler with an output rating of 2,332,400 btu will raise the temperature 1*F in 1 hour. (280,000x 8.33). Boiler outputs are rated in btu per hour . how many btu does it take to heat 15lb of water from 100 degrees F to 129 degrees F?
35kW is 119,424.97 BTU/hr
I think a Google search will help you with this one. Try: horse manure/btu or something like that.
Propylene has a lower heating value of approximately 21,500 BTU per gallon.
The average heating value of heating oil is around 138,500 Btu per gallon. Since there are approximately 3.785 liters in a gallon, one liter of heating oil would contain about 36,600 Btu.
114,000 BTU/gallon
114100 Btu
For regular gasoline, 125,000 BTU per US gallon
140,000 btu/gallon, nominal
Standard bath is taken to be 20 gallons at 8.35 pounds per gallon and 60 degrees F of heating = 10,000 BTU per bath in round numbers, assuming 100% efficiency water heating.
Standard shower is taken to be 10 gallons at 8.35 pounds per gallon and 60 degrees F of heating = 5,000 BTU per shower in round numbers, assuming 100% efficiency water heating.
In a gallon of gasoline, there is approximately 124,884 btu. BTU refers to British thermal unit. It is actually a traditional unit.
answer: 7680 btu 1 gallon= 8 lb 130F-50F=80F 12G*8LB*80F=7680 BTU
12,000 BTU/hr
76000
