Patricia,
Thanks for mentioning a valid point. Most of the pumps are new or thoroughly cleaned before a test, so clogging is not a major concern. When the tank is not in use, we chlorinate and filter the water to alleviate sediment, algae and other unmentionables.

I completely understand your explanation that the perforated holes do not in themselves release air, rather the holes facilitate the release of entrained air by keeping the turbulent flow on the discharge half of the test tank long enough for the air to be released to atmosphere.
Also, the tank...
Artisi,
I'm not quite sure I understand your reference to the hole size. ANSI/HI specifies that the inlet flow rate is to not exceed 1.5ft/sec. I can achieve that by many combinations of the following variables:
1) flow (gpm)
2) # of perforated holes
3) perforated hole size
The absolute...
I am in charge of rehabing an existing submersible pump test tank. The tank is 10'L x 8'W x 4.5'H with a working volume of about 2500 gallons, while the maximum allowable system flow is 2000 gpm. I want to separate the tank's inlet and discharge halves with a perforated baffle to 1)help control...
If your manager "never gives a 4", and you feel your potential for a better raise in salary is diminished because of that lower rating, it's time to find a new employer.
My previous employer left me at a similar crossroad. For the last two years I was there, my manager gave me several of the...
