propane flow rate

[scman1981]

Hi,
The data sheet of a boiler shows flow rate of propane 153.6 Nm3/h.
what is the calculation to find kg/hr flow rate.
would be a help. this is for my project report.

so this is what Google tells you about nm^3/hr ...
Nm3/h (normal cubic meters per hour) is a measure of gas flow rate at standard conditions of temperature and pressure (STP). The standard temperature for Nm3/h is typically 0°C (273.15 K) and the standard pressure is usually 1 atmosphere (101.325 kPa or 14.7 psi).

1) That should tell you what to do next.

2) Do the basic amount of searching first ! I literally typed "gas flow rate Nm^3/hr" into google to get this.

3) How do you convert volume to weight ?

Spoiler

density, as STP

hi,
Perfect gas law should help as long you are able to define Normal condition.Should be 0 C and 1 atm.
from gas law you will get the molar volume(22.4 l per mol) then the number of moles/h and the mass flow knowing the molecular weight of c3h8.
Noteroject report? This is so basic!
