The majority of TUTCO–Farnam Custom Product’s heaters are used to heat an air flow. When determining the power required to heat a stream of air, invariably two questions will come up. How much “stuff” do we have to heat up? In more technical terms, what is the mass flow rate? Ho...
The majority of Tutco–Farnam Custom Product’s heaters are used to heat an air flow. When determining the power required to heat a stream of air, invariably two questions will come up. How much “stuff” do we have to heat up? In more technical terms, what is the mass flow rate?
Standard cubic feet per meter (SCFM)is one of several ways to formally describe the flow rate of gases. SCFM measures how much ofthe matter that makes up a gas(or mixture of gases) passes through a given region of space per unit time. This is in contrast to the simpler and more commo...
which is defined as the mass of the gas per unit volume (m/V); d = m/V = P/RT. Isolating the mass of the gas being moved (m) and dividing by the time it takes to move it gives the following expression: m/t = d(V/t). In words, the mass flow...

SCFM is a set of specific parameters determined by the American Society of Mechanical Engineers (ASME), which are recognized across many industries. These SCFM calculations are based on atmospheric conditions (“standard conditions”) to measure air mass flow from an air compressor. ...

To convert mass to moles, via molecular mass, you don't need to know the temperature or the pressure. However, to convert moles to volume units you indeed need determine both, as cleary explained by Montemayor and Latexman. As a small digression: ideal gas molecules are considered by the...
volume is the same, the weight (mass) of the air is different. Figure 2 – Constant Volume Now consider a constant weight (mass) condition. A balloon filled with 31 actual cubic feet of air in Cartagena is then taken up to Medellin. The balloon now contains 38 standard cubic feet...
