Figure 6.1 - Leaks in a pump or a compressor |
Taking into account what was said in the « Technology » section, we can consider that:
In the case of a pump or a compressor, P1 pressure is below atmospheric pressure, thereby creating a depression. P2 pressure is greater than atmospheric pressure either because it has to overcome internal friction of the aspirated or compressed fluid, or because it is desirable to obtain pressure on this side of the blade.
Tolerated leaks will compensate P1 depression.
