# 300 psi coolant thru spindle = how may gallons per minute?

• posted

Hi I was wondering how to calculate the quantity of coolant oil comes out of the tool. It is a milling machine with 300 psi.

300 psi coolant thru spindle = how may gallons per minute?

Thanks a lot.

How large is/are the passageway(s)?

More importantly, how large is the smallest passageway? I presume the distance is not very far so wall friction won't matter much.

~20,000 GPM should be do-able provided you have enough horsepower.....

Smartech:

Here is one formula. GPM = 29.7d²?P

Let's say you were using a coolant through drill with two coolant holes that were each 1/8" in diameter:

29.7 X (.125 X .125) X (square root of 300 psi) 29.7 X .015625 X 17.32 = 8 GPM

(Since there are two coolant holes in your drill) 2 X 8 = 16 GPM

Now this is just a rough estimate, since it doesn't take into consideration any friction losses, or viscosity change due to the soluble oil in the water, or the exact coolant hole size of your drill's coolant holes.

I guess the square root symbol didn't come through. It's supposed to be (square root of P).

Hehe...easy there Bob, just couldnt resist letting that one sit eh ?

Okay then next question:

( After Katrina hit ), just how many EMD SD70* locomotive would it have taken to have been able to have pumped all of the water out of downtown New Orleans given a total time period of say 24 hours ?

• posted

None. EMD SD70's won't run submerged. LOL

Do I get a prize?

Yeah you do I think garlic has it though something about arguioing with retards and the internet

Hey on a serious note if anyone is running dual turret fanuc g68 /g69 appreciate any help I think I have this bugger finally figgered its seeming like parm 31 on a 3t maybe differnt parameter on the others but you need it so as to refrence the distance that gets you from g28 to the point whrer you sync bush is centered between the upper / lower turret ideally perfectly centered.

OAB:

Just had some time to play around, and was kind of curious myself.

Sorry, I don't have THAT much time, since there is not enough information to even START to calculate an answer. LOL

Fair enough then, and so now *IM* off to your recent post about health care though I pay 100% still a story there coming from me shortly.

Stay tuned.........

Couldn't they run submerged *IF* they had snorkels for the intake and exhaust?

Not without electrocuting anything within a mile or so. EMD means "ElectroMotive Division" and that's how they work Bob. The things are giant gensets.

Not enough information. Get a 3" sanitary elbow and some pipe. Place over tool, blow coolant and collect and measure in bucket.
