The absolute value of FP must be greater than the minimum fan pressure, “MF”, shown in Table 8, and
greater than the calculated factor using the K2 value from the table as follows:
To determine the flow for a particular fan pressure FP:
Check that the measured value for FP meets the two conditions based on MF and K2. If so, find the N, K,
K1, and K3 values in Table xxx (based on the type of fan and the Range Configuration being used), enter
those values along with the values measured for FP, and RP into the Flow equation stated above and
calculate the result.
