Hi Chet - yes that would be correct. Bernoilli's equation assumes no shear stress which would be involve friction. So it doesn't matter how long the pipe is or where the pressure drop occurs even though it would have to be in the transition between the vessel and the pipe.

Hi Chet - something isn't right. At a flow rate of 800,000,000 cfm, the velocity of the air blasting out of the pipe would be over 69,000 miles per hour! That's just not realistic at all. Since then I used Bernoulli's equation and got a better result of 256 ft/sec

Hi Steamking. I just tried another way to solve it and I think it worked using Bernoulli's equation. Please check this if I am right. By using Bernoulli's equation we assume: no friction, no shear stress, only steady flow, and density is constant. Given that the length and diameter of pipe is...

I don't understand your response. I don't know the velocity or the flow rate. That's what I'm trying to find out. And I can't calculate the Reynolds number without the velocity or flow rate.

I looked at that and I need to know the velocity or flow rate of the air.

Homework Statement The horizontal pipe is very large and long: 100 feet in diameter and 1500 feet long with an infinite supply of air on both ends. The pressure difference between the two ends is 0.6 psi. I assume friction is near zero as the pipe is so big so I ignore it. What is the...
