One.
Any amount of heat added to any material will heat that material. Obviously, the amount of increase in heat is dependent upon the material's specific heat, its mass, and the amount of heat applied.
**Using the assumption that you wish to heat a room of 43200 cu.ft. with 3 air exchanges per hour (average), from 40 degrees to 70 degrees fahrenheit (average for New England, in the fall), then the amount of btu's per hour required would be 311,040 btu/hr.*
* {multiply volume x 0.24 btu/hr (specific heat of air) x 3 air exchanges/ hr x [temperature required - ambient temperature]}.
To convert cubic feet to gallons of propane, you first need to know the specific gravity of propane. On average, the specific gravity of propane is around 0.504. Therefore, 1400 cubic feet of propane would be approximately 702 gallons (1400 cubic feet / 7.48 gallons per cubic foot).
136 cubic feet / hour = 3.851 cubic metres / hour. 1 metre = 3.28 ft, so 1 cubic metre = 3.28^3 cubic feet. Therefore you divide 136 by 3.23^3
To convert cubic feet per hour to liters per minute, you can use the conversion factor: 1 cubic foot = 28.3168 liters and 1 hour = 60 minutes. So, you can multiply the cubic feet per hour value by 28.3168/60 to get liters per minute.
To convert cubic meters per hour to BTUs per hour, you need to know the type of gas. Multiply the cubic meters per hour by the energy content of the gas in BTUs per cubic meter to get the BTUs per hour.
There are approximately 0.02832 cubic meters per hour in a cubic foot per hour.
60 cu ft/min=1 cu ft/hr
cubic feet per hour x 0.016666667 = cubic feet per minute
106 cubic feet per hour (cfh) of LPG is approximately equal to 4.94 gallons.
To convert cubic feet to gallons of propane, you first need to know the specific gravity of propane. On average, the specific gravity of propane is around 0.504. Therefore, 1400 cubic feet of propane would be approximately 702 gallons (1400 cubic feet / 7.48 gallons per cubic foot).
Cubic feet per hour x 7.48 = gallons per hour
300 cubic meters per hour is about 176.57 cubic feet per minute.Formula: Cubic meters per hour x 0.5886 (rounded) = cubic feet per minute
136 cubic feet / hour = 3.851 cubic metres / hour. 1 metre = 3.28 ft, so 1 cubic metre = 3.28^3 cubic feet. Therefore you divide 136 by 3.23^3
1 liter per hour equates to about 0.0353 cubic feet per hour.
You would have to know the number of revolutions per hour.
Liters of oxygen gas per hour x 0.0353 = cubic feet per hour
Formula: cubic feet per hour x 7.481 = US gallons per hour (use 6.229 if you want to convert cubic feet to Imperial gallons)
Well let's see... theres 60 minutes in an hour. So if youre going 1 cubic foot a minute, you're going 60 cubic feet an hour.
