Conversion and its related terms yield and selectivity are important terms in chemical reaction engineering.They are described as ratios of how much of a reactant has reacted (X — conversion, normally between zero and one), how much of a desired product was formed (Y — yield, normally also between zero and one) and how much desired product was formed in ratio to the undesired product(s) (S ...
The flow is proportional to the absolute inlet pressure, so the flow in scfm would equal the C v flow coefficient if the inlet pressure were reduced to 2 psia and the outlet were connected to a vacuum with less than 1 psi absolute pressure (1.0 scfm when C v = 1.0, 2 psia input).
≘ 10 −8 V = 10 −8 V statvolt : statV ≘ c⋅(1 μJ/A⋅m) = 299.792 458 V: volt (SI unit) V The difference in electric potential across two points along a conducting wire carrying one ampere of constant current when the power dissipated between the points equals one watt. [32] = 1 V = 1 W/A = 1 kg⋅m 2 /(A⋅s 3) = 1 J/C
Reversing this yields the formula for obtaining a quantity in units of Celsius from units of Fahrenheit; one could have started with the equivalence between 100 °C and 212 °F, which yields the same formula. Hence, to convert the numerical quantity value of a temperature T[F] in degrees Fahrenheit to a numerical quantity value T[C] in degrees ...
In thermodynamics, the Volume Correction Factor (VCF), also known as Correction for the effect of Temperature on Liquid (CTL), is a standardized computed factor used to correct for the thermal expansion of fluids, primarily, liquid hydrocarbons at various temperatures and densities. [1]
ν = scan rate in V/s; R = Gas constant in J K −1 mol −1; T = temperature in K; The constant with a value of 2.69×10 5 has units of C mol −1 V −1/2; For novices in electrochemistry, the predictions of this equation appear counter-intuitive, i.e. that i p increases at faster voltage scan rates. It is important to remember that current ...
In hydrometry, the volumetric flow rate is known as discharge. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol q, with units of m 3 /(m 2 ·s), that is, m·s −1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per ...
With this conversion from SCCM to kg/s, one can then use available unit calculators to convert kg/s to other units, [5] such as g/s of the CGS system, or slug/s. Based on the above formulas, the relationship between SCCM and molar flow rate in kmol/s is given by
