What is Nm3? How is It Different from m3? - Airpressa Nm3 refers to the volume of a gas under “normal” predefined standard conditions of temperature and pressure, typically 0 degrees Celsius (273 15 Kelvin) and 1 atmosphere of pressure (101 325 kPa)
Gas flow calculation in Nm³ hr and Sm³ hr - EnggCyclopedia Table of content: Normal meter cube per hour Standard meter cube per hour Gas flow calculation in Nm³ hr Sm³ hr Normal meter cube per hour Normal meter cube per hour (Nm³ hr) is a unit of measurement used to express the volumetric flow rate of gases under standard conditions of temperature and pressure (STP)
Understanding NM³, SM³ and AM³: A Guide to Gas Volumetric Flow Measurements When measuring gas flow in industrial applications, it’s essential to understand how temperature and pressure impact the volume of gases This article explains the concepts of Normal Cubic Meter (NM³) and Standard Cubic Meter (SM³) — two critical terms for specifying gas flow in a consistent manner regardless of fluctuating temperature and pressure conditions
Difference between Actual, Standard and Normal Flows The two common standardized volumes are standard cubic feet (scf) and normal cubic meters (Nm3) A standard cubic foot of gas corresponds to 1 cubic foot of gas at 32 °F (0 °C) and 14 6959 PSI, and a normal cubic meter of gas corresponds to 1 cubic meter at 20°C at 101 325 kPa (NIST Reference)
NM3 vs. M3 — What’s the Difference? NM3 (Normal Cubic Meter) measures gas volume at standard temperature and pressure conditions; M3 (Cubic Meter) measures volume in its natural state, without standardizing conditions
