Answer / carl_ellis
Answer:
The flow rate at 50.0"wc will be 141.4% of the flow rate at
25.5"wc.
Reason:
The design maximum flow rate at 25.0" is 100.0% flow rate.
Flow rate is the square root of the percentage of flow at a
given DP.
The flow rate at 25.0"w.c. DP is the square root of 1.00 (or
100%)
If the DP doubles from 25.0 to 50.0, then the DP increases
from 100% at 25.0"wc to 200% at 50.0"wc
The flow rate at 200% DP increases by 141.4% because the
square root of 2.00 (or 200%) is 1.414.

Answer / enka group iraq
Ans;- A simple calculation is as follow :- Q1 / Q2 = √DP1/√dp2
Q1= Q2 X √DP1/√dp2
Q1 = new flow factor, Q2 = existing flow factor
DP1 = transmitter new range DP2 = transmitter existing range
Q1 = Q2 X √50/25 = Q2 X 1.41
The new flow factor will be 1.41 times higher then the existing flow factory
