1 cubic foot = 0.0283 cubic meters. Estimates put the average energy density of the present day Universe at the equivalent of 5.9 protons per cubic meter, including dark energy, dark matter, and baryonic matter (ordinary matter composed of atoms). It is expressed as grams of moisture per cubic meter of air (g/m3). The maximum absolute humidity of warm air at 30°C/86°F is approximately 30g of water vapor – 30g/m3. Density of air at standard conditions is 0.075lb/ft3. Step 4 This step only applies to imperial meters. This is a conversion chart for normal cubic meter of natural gas (Natural Gas Energy Equivalent). 10-3 kg/m 3 = g/m 3; Example - Moisture Carrying Capacity in Heated Air. Though the density of air will vary due to differences in temperature, moisture content, and altitude, a cubic meter of air at sea level weighs approximately 1.2 kilograms (2.6 lb.). So it takes .005 watts to heat 1 cubic foot of DRY air 1 degree F. This is for dry air, the easiest way to do it is get a Psychrometric chart and plot the temp/humidity change you are after and calculate the change in enthalpy of the air in BTU's. Cubic feet and cubic meter are both measures of volume. In a cubic meter of empty space, there is about [math]10^{-9}[/math] Joules of energy. If 1 Btu equals 1055.1 J and 1 ft 3 equals 0.028316 m 3, then 1000 Btu/ft 3 multiplied by 1055.1 J and divided by 0.028316 m 3 equals 37 MJ/m 3, which is the average energy content of natural gas. The objective of compressed air energy-savings projects is to reduce the kWh consumed by the electric motors powering your air compressors. Please use the calculator below to achieve an understanding of the kWh consumed (or saved) in your compressed air system. Air is heated from 20 o C to 50 o C.. from the table above the maximum moisture content in air at 20 o C is 17.3 g/m 3, and; the maximum moisture content in air with temperature 50 o C is 83 g/m 3 ; The increased ability to carry moisture can be calculated as However, since we will ultimately be expressing units in metric form we need to get the units into metric form. b) Suppose a particular turbine has blades with a radius of 42m and is able to capture 37% of the available wind energy. The energy density of oil is 35 to 45 gigajoules (10,000 kWh) per cubic meter One gigajoule equals one billion joules, and there are 3,600,000 joules in a kWh. 2: Enter the value you want to convert (normal cubic meter of natural gas). The amount of energy of natural gas can be converted from Btu per cubic feet to Joules per cubic meter. At the site of a wind farm in North Dakota, the average wind speed is 9.4 m/s and the average density of air is 1.3 kg/m^3. A BTU= 0.29watts. Then click the Convert Me button. A cubic meter of ocean water weighs approximately 1,025 kilograms (2,260 lb.). Jany Tran -- 2002 a) Calculate how much kinetic energy the wind contains, per cubic meter, at this location. Convert from cubic feet to cubic meters. The maximum absolute humidity of cold air at 0°C/32°F is approximately 5g of water vapor – 5g/m3. To switch the unit simply find the one you want on the page and click it. You can also go to the universal conversion page. 1 Btu per second = 1.055 kilowatts 1 Btu per second = 1.415 horsepower 1 Btu per second = 1.434 metric horsepower 1 Btu per second = .252 kilocalories per second 1 kilowatt = .9478 Btu per second 1 kilowatt = 1.341 horsepower 1 kilowatt = 1.36 metric horsepower 1 kilowatt = .2388 kilocalories per second 1 horsepower = .7457 kilowatts This energy is mainly caused by virtual particles. Absolute humidity is the measure of water vapor (moisture) in the air, regardless of temperature. The atoms account for only 4.6% of the total energy density, or a density of one proton per four cubic meters. So, either multiply by 0.0283 OR divide by 35.315. These particles have a really short life, and undetectable physical effects.
