Arrow Nm3/hr to m3/hr

how do u convert 1 Nm3/hr of HCl to m3/hr?

Does the conversion require any other parmaters like density,etc.?
Is the conversion for 1Nm3/hr of HCl to m3/hr standard , i.e can i use the conversion rate for any other gases also?

The N stands for Normal, meaning standard temperature and pressure.

At standard temperature and pressure, then Nm3/hr = m3/hr

Is the 18 psi absolute or gauge? I have assumed absolute below

Since the same moles of gas are involed P1*V1/T1 = P2*V2/T2

So, V1 = V2 *(P2/P1)*(T1/T2)
Standard pressure 101/325 kPa is about 14.7 psi

Assuming "as measured" is 1 m, 18 psi, 35 C, volume at normal is
V1 = 1 m x 18 psi/14.7 psi * 273.15 K/(35 + 273.15 K) =
1.0854 Nm

The N stands for Normal, meaning standard temperature and pressure.

At standard temperature and pressure, then Nm3/hr = m3/hr
In this case, what would be clasified as normal? From a pharmaceutical perspective, normal and standard are 2 totally different aspects of the same criteria.

As regards gases, "normal" is always at 101.325 kPa and 0 C. "Standard" is mostly used with "english" units, eg standard cubic feet, and uses the same standard pressure. Unfortunately, different industries use different (non)standards, and the temperature could be 15 C, 60 F, 20 C, 25 C and possiblly others.

By stating the volume at normal or standard conditions, it becomes a disuised form of molar or mass flow. At normal, a number of grams of gas equal to the molecular weight (1 mole) will occupy 22.414 L of volume). The factor is slightly different (by ideal gas laws) at the various (non)standard temperatures.

Thanks for that answer! I presumed the N meant newtons and was very confused.

Thanks
