Figure P6.95 provides steady-state test data for a control
volume in which two entering streams of air mix to form a
single exiting stream. Stray heat transfer and kinetic and
potential energy effects are negligible. A hard-to-read
photocopy of the data sheet indicates that the pressure of
the...

Hi there, my name is Peter and I am currently a Computer Engineering major at UW-Milwaukee.
I am enrolled in physics 209-401 with Mr. Robert Wood and I actually know Greg who created these forums!
So... now I'm going to use them to ace this class!
With a little help from my brain. And all of...
