It's been a long time since I had to do any calculus and longer still since I had to deal with ideal gases but now I'm confronted with both.
The problem setup is this:
Air is coming into a compressor at a known mass rate, pressure and temp.
It's being compressed to fill a known tank volume at at given pressure and temperature. Once that pressure is reached the regulator allows air to leave maintaining the same pressure.
I want to plot a graph with the Flow rate vs time.
I was able to get a formula (in terms of Volume, Pressures, Temperature and time) that graphed but it didn't contain the mass flow rate. Seems to me that's important and thus the answer trailed off to almost Zero at the time to fill the tank. I know that's not right. At the moment the regulator releases air the flow rate will remain constant.
the basis is Mass Flow Rate = constant
start making substitutions, intergrating .. bla, bla, bla .. I get lost and need a beer.
Can you help an old fart out here?
