In a bourbon distillery plant, the refined product, approximated as 40% by weight ethanol, 60% by weight water, is pumped through a plumbing system. At the OUTLET, where the inner diameter of the pipe is 5.08cm, the product fills an aluminum open cylinder (Diameter .442m, height 1.26m) in 98.9 seconds. At the inlet of this pipe the diameter is 7.62 cm and the pipe is 3.85m above the cylinder. the density of the product is 922kg/m^3(adsbygoogle = window.adsbygoogle || []).push({});

a) what is the outlet speed of the product?

b) what is the gauge pressure at the inlet of the pipe (diameter 7.62cm)

WHEW! okay, question a....

the outlet speed: it fills an aluminum open cylinder in 98.9 seconds. first step, find the volume of the cylinder? the volume of a cylinder is given by: pi*R^2*length, right? so: pi(.221^2)1.26m = .19m? my units are wrong, and the volume seems AWFULLY small.

lets roll with it, though...

it fills this volume in 98.9 seconds. (1.65 mins). Now, I have the volume filled, and the time it took. (should be .019L/1.65min) how do i get this into useable figures (like L/min)?

now for question b:

the gauge pressure...

it wants the guage pressure at the inlet of the pipe. (diameter 7.62cm)

I can't do this until i get the outlet speed, correct? even if i had the outlet speed, i'm not sure how to obtain the gauge pressure?

i know this is really long and laborious.... but i've been working pretty hard on this, and any help would be appreciated. thank you all.
