Please help to convert flowrate kg/minute to cubic meter
kindly help me to solve this conversion problem.
I'm selling CNG compressed natural gas methane; the most dispenser standard are using kg/minute  for flowrate unit. and i want to convert the unit to normal cubic meter for our standard volume.  what's the formula ?  what the common for methane gas density if we are not sure, lets assume that the density of methane is 0.667kg/m3 so i would like to know the volume; 1 kg/minute = ??? NM3 Highly appreciated for your help

The second problem is natural gas is mostly, but not purely, methane. The impurities are enough that the average molecular weight and density are noticably different from pure methane. At 101.325 kPa and 0 °C, this site http://www.engineeringtoolbox.com/ga...ityd_158.html gives a density of 0.717 kg/m³ for pure methane, and 0.7  0.9 kg/m³ as typical range for natural gas. For a rough conversion, you could use midpoint, 0.8, but for a conversion that meets "legal for trade" accuracy, you probably need a measured density and quantitative chemical analysis (if you want heat content) for the gas you are selling. Using the 0.8 figure, 1 kg/min is also 1.25 m³/min; just divide by the (hopefully correct) density value.

Dear John,
appreciate for your replied

Re: Please help to convert the following
The calorific value is app. 10.000 kcal/kg gas or 8.000 kcal/Nm3.
1.400.000 x 800 / 10.000 kg/day = 112.000 kg/day or 112 ton/day Would like to know the value in m3. Thaks very much juanpablogimenezj@gmail.com

112000 kg/day x 1 Nm³/0.8 kg = 140 000 Nm³/day.

if i have a garages room ( 20m*12m*2.25m),i need ur help to calculate the air flow required in meter cubedper houre

Re: Please help to convert flowrate kg/minute to cubic meter
The volume of your garage is just the product of those dimensions, 540 m³. However, different building codes require different rates of air exchange per hour. Two exchanges per hour would require 1080 m³/h.

Re: Please help to convert flowrate kg/minute to cubic meter
Dear mac daddy and JohnS,
THere used to be a conversion table on the Emerson Web site for the micromotion meter. There is a lot of pressure on CNG equipment makers to rate their Cv factors so one can calculate the pressure needed to dispense gas at the 150kg/min rate the meteres are designed for.

THe Emerson Micromotion CNG50 data sheet gives 7550Nm3/hr equal to 100kg/min.
