1. AIR VOLUME IS GENERAL SHOWN IN TERMS OF:

(1) STANDARD STATE (Qs): AT 20c ・10332mmAq・AND RH. 65%
(2) NORMAL STATE(Qn): AT0°C ・10332mmAq・AND RH. 0%

2. PERFORMANCE TABLE SHOWN THE CAPACITY AT THE STANDARD SUCTION STATE.

3. PERFORMANCE TABLE SHOWN THE PRESSURE AT THE STATIC PRESSURE

4. VOLUME CONVERSION FORMULA

`Q_2= Q_1*[P_1]/[P_2]*[T_2]/[T_1]`

`Q_1(M^3`/`min)`: AIR VOLUME IN, `P_1`(mmAq), `T_1(K)`
`Q_2(M^3`/`min)`: AIR VOLUME IN `P_2`(MmAq), `T_2(K)`

5. PRESSURE CONVERSION FORMULA

(1)FOR PRESSURE `Ps =( [10332+P_2]/[10332+ P_1]-1)*10332`
(2)FOR VACUUM `Ps =( [10332+P_1]/[10332+ P_2]-1)*10332`

`P_1`: SUCTION STATIC PRESSURE  `P_2`: DISCHARGE STATIC PRESSURE  `Ps`: STATIC PRESSURE IN CATALOG

6. EXAMPLE

OPERATING SPECIFICATIONS:
AIR VOLUME 5.16 m³/min
SUCTION STATIC PRESSURE -500 mmAq
DISCHAREGE STATIC PRESSURE +4260 mmAq
SUCTION TEMPERATURE 40℃

CHOICE: AIR VOLUME (5.16 m³/min) CONVERTS TO STP STATE

`Q =5.16*[10332-500]/10332*[273+20]/[273+40]=4.60m^3`/`min`

STATIC PRESSURE CHANGED TO:

`Ps =( [10332+4260]/[1033-500]-1)*10332=5000 mmAq`
