This is a real world engineering design problem. I'm part of a large group of engineers in their sophomore to senior years(mostly meche and aero) building a liquid engine. We meet every week to discuss calculations, we have a bunch people who all attempt the problem individually. I'm probably...
If I'm designing an injector for a rocket engine, I have a specific mean flow rate (m/s) that must be met due to the pipe diameter and the required mass flow rate.
I've calculated all the pressure drops due to lost work from friction, valves, and orifice geometries (not from change in area, but...
