Industrial Contractor Supply
Physics Homework, help greatly needed!?
Suppose that you are asked to design some of the plumbing in an industrial setting. Specifically, you are asked to advise the contractor on the pressure needed to send alcohol though some pipes to supply an industrial process. The process needs
2 liters per second (1 liter = 1000 cm3) of alcohol to be delivered. (Alcohol has, at 20 degrees Celsius, a density of 0.79 g/cm3 and a viscosity of 0.0012 Pa sec.) The pipe to deliver the alcohol is 12 meters long and has a diameter of 1 cm.
(a) What pressure difference must be maintained across the 12 meter long pipe to deliver this much alcohol?
(b) If you were to recommend that the diameter of the pipe be doubled, what pressure difference would be required in that case?
Go to the site below and post your question on the physics question and answer board. Somebody will answer and explain the steps to work the problem.
