The first four parts reviewed the crude-to-gas ratio at 50X, the impact of increasing NGL production on prices, the uplift value provided by gas processing, and who gets all the money. The British Thermal Unit (BTU) is the basic measure of heat energy in the Imperial system. ie: 860,000. 34 = about 10,000 Btu/kwh. The graph at the bottom represents the ramp rate of outlet temperature over time given the parameters in the tool. Since tankless water heaters supply endless hot water, you don't have to worry about capacity, but instead, think in terms of water flow rate. Gallons Per Minute (GPM) is the key when it comes to sizing tankless water heaters. Then, add up their flow rates (gallons per minute). A ton of refrigeration is 12,000 BTU / hour [1, 2] which corresponds to the amount of energy necessary to melt on ton of ice in 24 hour. Heat Load (BTU/Hr) = GPM X 500 X ° Range of cooling If the Heat Load, and one of the other two factors are known (either the GPM or the ° Range of cooling) the other can be calculated using this formula. ) Gallons U. per hour and 2000 lbs. 28 btu/hr to produce 1 pound of steam at the above conditions.
