Hello,
I'm looking at this problem which states:
"A parallel air flow along a semi infinite flat plate has undisturbed parameters as follows: "
Then they list the speed, temprature, viscousity and pressure.
"Demonstrate that the boundary layer can treated by means of incompressible...
Homework Statement
A piston-cylinder device contains 1.2kg Nitrogen gas at 120 kPa and 300K. The gas is now compresses slowly in a polytropic process during which PV^1.3 = constant.
The process ends when the volume is reduced by one-half.
Determine the entropy change of Nitrogen during this...
