Issues with temperature and pressure compensation and standard cubic meters per hour (Nm3/h)
Thread Content
It’s simple to perform temperature and pressure compensation on a certain flow rate in a DCS, but if one has to calculate it manually, then a formula for temperature and pressure compensation is needed. So what is that formula for temperature and pressure compensation? The unit for compressed gas flow rate is generally m3/h; if temperature and pressure corrections are applied to the compressed gas flow rate, then its unit must be Nm3/h, right? The unit for steam flow rate is generally kg/h; if temperature and pressure corrections are applied to the steam flow rate as well, what will then be its unit? Is it kg/h or Nkg/h?
The volume of a gas changes as pressure changes, but its mass remains constant.
