2.
Incline
Manometer/Magnahelic
Example 1:
Return ESP after Filter
0.20 in.w.c.
Supply ESP before Coil
0.40 in.w.c.
------------------------------------------------------
Total
ESP
0.60
in.w.c.
Example 2:
Return ESP before Filter
0.10 in.w.c.
Filter Static Pressure Drop @ 2000 cfm 0.10 in.w.c.
Supply ESP after Coil
0.20 in.w.c.
Coil Static Pressure Drop Wet
0.20 in.w.c.
------------------------------------------------------
Total
ESP
0.60
in.w.c.
Both Examples 1 and 2 are correct. Example 1 ESP readings were taken as laid out in static pressure reading location diagrams (Figures 7 - 9).
Example 2 readings are taken as described. The coil and filter static pressure drops were taken from the manufacturer’s product data sheets with the
assumption that 2000 cfm is being delivered.
