Corrected Flow is the mass flow that would pass through a device (e.g. compressor) if the inlet pressure and temperature corresponded to ambient conditions at Sea Level, on a Standard Day (i.e. 14.696lbf/in²,288.15K).
Corrected Flow ,, can be calculated as follows, assuming Imperial Units:
Corrected Flow is often abbreviated to wc or wr (for referred flow).
So-called Non-Dimensional Flow ) is proportional to Corrected Flow:
The equivalent equations for Preferred SI Units are:
Nomenclature:
P Stagnation (or Total) Pressure
T Stagnation (or Total) Temperature
w Real Mass Flow
δ Referred Pressure
θ Referred Temperature
In relative form, Corrected Flow, Referred Flow and Non-Dimensional Flow are all measures of axial Mach number.
The other axis is some measure of flow, usually non-dimensional flow or, as in this case, correctedflow, but not real flow.
Under these conditions, there is a slight scatter in flow between the speed lines in the 'choked' region of the map, where the flow for a given speed reaches a plateau.
A falling nozzle flow capacity tends to reduce the LP turbine pressure ratio (and deltaH/T).
The correction factor is 0.906, meaning that the flow of 1,3-D is 90.6 % of the maximum flow capacity of the meter for water (2.43 gal/min).
When this is the case, the maximum 100% flow rate for the meter must first be converted from the fumigant it is calibrated for to water (use of equation 2), and then from water to the fumigant which is to be applied in the field (use of equation 1).
The correction factor for methyl bromide to water according to equation 2 is 1.3153 (ie., the square root of 1.73).
