Downstream.. Exit to atmosphere

Hi. Is there any way to calculate airflow out of a tube (into atmosphere) with only the pressure and cross sectional area of the tube?

I agree that it is very simplistic. But that's what I'm looking for :) just want to make sure my thinking is right. In any case this calculation will be on the low side for the reasons you mention

I meant18-26%

Hi all, So I was thinking about how you could calculate the calories burned when lifting weights. The actual energy requirement should be simple enough if I'm not mistaken : Amount of weight in kg * distance traveled per repetition in m * g constant * number of reps = Joule expenditure Then...

I am posting this here instead of "Science and math textbooks" because I am looking for suggestions on an easy reading but educational book, not a workbook. I am by no means an expert, but I have a solid backgound in math and physics from college (Engineering), as well as self-study with...

We're in college, no need for robotic girlfriends! :D haha Saving that project for later in life :D

*Looking for cool ideas for a Bachelor project!* Hi everyone! We are a group of 4 mechanical engineering students that will be doing a Bachelor project for a local hydraulic-systems company. We are just thinking of/looking for ideas...it will not be produced so cost is not a concern. Pretty...

Forgot to mention, Installed on a boat :D

A couple friends and I were brainstorming an idea today and thought of a way to make a pump using the waves in the ocean for enrgy. So what it comes down to is say a 6cm i diameter steel ball in a tube, each side of the tube could have "pillows" that are part of a "membrane-pump". When the...

Ok. I did not realize that no one will show me the solution here or I wouldn't have bothered posting. No point then is there. Thanks for the input everyone, I can't find a delete button maybe a mod can delete the thread for me?

Ok so I am working on this problem and can only get through the first question, the second question keeps stumping me. I have uploaded the question along with my calculations for part a so you can see what I'm doing. ----- A object of mass (m) is shot vertically up with V0 200 m/s...

I have noticed when sitting in the sauna that when you throw a couple cup sof water on the sauna rocks that the thermometer on the wall drops in temerature before slowly starting to climb back up, at the same time the thermometer drops your skin feel slike you have doubled the temprature! I...
