1. The value in the table is obtained under the following condition:
a.air pressure is 0.1013Mpa 760mmHg ;
b.inlet water temperature is 20℃ ;
c.relative air humidity is 70% .
2. The value is obtained when the supplied water amount is the suction pressure -0.05Mpa( 400mmHg). It can be bigger than this when it reaches utmost vacuum.
3. The performance difference will not exceed±10%
