This problem involves a Blending Plant. The PI, base oil mix, and VII are blended together in a hot tank and then the finished product goes to the bottling machine.

The velocity (flow rate) of the oil at the bottling station is 2.38 meters/s through a circular Pipe of 26 mm Diameter.

How long (in time - seconds) does it take to fill a Quart bottle?

(1 Quart = 0.946 L) and 1 L = 1X10-3 m^3).

I.e, 1 Liter equals 10 to the minus 3 cubic meters.

Hint 1: First find the Volume flow rate (or sometimes called, The "Volumetric Flow Rate") in Liters/second, then determine how long it takes to fill the bottle.

Hint 2: for the simple equations you will need see:

https://www.khanacademy.org/science/physics/fluids/fluid-dynamics/a/what-is-volume-flow-rate or Wikipedia.


This question is open to all, but let's please allow non-engineers, non-Tribologists and non-chemists time to research the question and to respond before answering.

Q = A x V

Liters/sec = sq cm x cm/s

so rearranging:
sec = (sq cm x cm/s) / liters

= 946 cm^3 / ([2.6^2 x .7854] cm ^2 x 238 cm/s)
= .749 sec to fill the quart bottle.

Volumetric flow rate is 1.263 liter/sec

Would any non-engineers, non-Tribologists or non-chemists like to respond with their calculations and numbers?

This one should exclude mathematicians and physicists, too, Mola. wink

Mr Harmon gave the correct answer with one approach to the problem.

My step-by-step approach is somewhat different and is found in the pdf.

With hints and some good links, I was hoping for more responses but Mr. Harmon gets the virtual BITOG Mug with the thumbsup Emblem and a virtual case of XWXX Full Synthetic oil.

Either way, I hope this problem was an educational one.
