Subject:
ENA/CPC/C1 - New pump slightly under pressure
DataStreams:enaaoscpcfC1.b1, enaaoscpcfC1.a1, enaaoscpcfC1.00
Description:
Due to a pump failure, a different pump was used on the system.  The orifice pressure was 
lower with this additional pump and the system may have been slightly under the pressure 
required to maintain critical flow on the CPC's critical orifice. Flow rate measurements 
during this time show very little change in the output flow rate.
Suggestions: 
Use data with caution.
