Dry air at 0º C has a density of 1.29 kg/m³

Just divide the kg/hr by 1.29 to get m³/hr

kg/hr / (1.29 kg/m³) = m³/hr

Different temperatures will have a different density. Humidity and pressure also affects it.

Water has a density of 1 kilogram/liter, or 0.001 kg/m³

to convert kg/hr to m³/hr you would divide by 1000

The density of gas differs, depending on the gas, you will need to post the type of gas.

I'm sure the density units are wrong and that is 870 kg/m³
Just divide it into 38000 kg/h to get 43.7 m³

a dm³ is equal to 1 liter. You won't find any natural materials on earth with density of 870 kg/L

You need to know the temperature and pressure of the steam, and consult steam tables in which the the density is tabulated. It varies greatly according to conditions. Once you have the density (in kilograms per cubic meter), just divide by it to convert.

First you need to determine the enthalphy of the steam, you need to use steam tables or a lookup calculator such as steamtablesonline. At an absolute pressure of 41 bar and 30 °C, the specific enthalpy is 129.5 kJ/Kg.

The energy in the steam is 129.5 KJ/Kg * 153160 Kg/Hr yields 19,800,000 KJ/Hr.

There are 0.0002778 kw-hr per KJ. Therefore

19800000 KJ/Hr * 0.0002778 kw-hr yields 5510 kw. Note that this is not kw-hr you requested and can not be converted to kw-hr.

The temperature can't be 30 °C at the specified steam pressure. Did you just assume saturated steam, or make some other specific assumption about what temperature was really meant? I assume a digit is missing, as the pressure of 30 °C "steam" (commonly called water vapor at this temperature) is a small fraction of 1 bar.

185 °F = 85 °C. You need the density at 85 °C. Assuming the SG is the ratio of the density of the mixture at 85 °C to water at 85 °C, we need the density of water at 85 °C. My Handbook of Chemistry and Physics gives 968.62 kg/m³. Multiplying by 0.88, the mixture is 852.4 kg/³.

43000 kg/h x 1 m³/852.4 kg = 50.45 m³/h

JohnS

580 kg/h Nitrogen convert m3/f

At what temperature and pressure? The volume of a gas is a meaningless concept unless temperature and pressure are specified. N2 has a molecular weight of 28 g/mole so this is 20.7 kmol/h. Use ideal gas law to work out molar volume and temperature and pressure of interest, or substitute directly in ideal gas law, PV = nRT.

As an aside, the volume varies with temperature and pressure, so either a mass or molar flow rate is easier to keep track of if conditions vary in your process.

If this is a gas, you need to know the temperature and pressure. Then you need either the ideal gas law, or a better equation of state if compressibility (Z) is an issue, to calculate moles per hour. Then multiply by molecular weight.

Without temperature and pressure, the volume of a gas has no meaning. gas expands to fill the space.

Divide by the density of the material in kg/m³.
If you don't know the density, you have to look it up in a reference or measure it. Note that density is a function of temperature, and, for gases, pressure, as well as the specific material.

Use either the formula or cloesest table value from this:
http://en.wikipedia.org/wiki/Density_of_air
If you use the formula, you must use absolute pressure and temperature.

Note that for moderate to high accuracy, you must also specify and consider how moist the air is. As the molecular weight of water is less than the average molecular weight of dry air, humid air has lower density.

Dry air at 0º C has a density of 1.29 kg/m³

Just divide the kg/hr by 1.29 to get m³/hr

kg/hr / (1.29 kg/m³) = m³/hr

Different temperatures will have a different density. Humidity and pressure also affects it.

Robert, can you expand on the comment about how temperature affects density and how humidity and pressure affect conversion? I am dealing with air in approximately 100 DegF temperature and 65% RH, with pressure in the 16 psig area.
