Hey guys,
I'm new to fortran and I'm having a slight problem. I put my code below as reference. I first set up a my known values. Then I used an equation to solve for v. After I solve for v I then computed c which involves v.
What I'm now trying to do is to loop the value I got for c back...

The problem is to calculate the flux emanating from the exhaust of a jet engine.
The air gas velocity from a jet engine varies linearly from a maximum of 300 m/s at the center of the circular exhaust opening to zero at the edges. If the exhaust diameter is 1.6 m, find...
Hello,
So I'm facing some difficulties. I'm using a DC voltage supply and connecting it to a PIC Board. The AC adapter that comes with the board outputs 9V DC. To be safe I'm just using 5V from the DC voltage supply. When I connect it to the board the reading from the voltage supply drops to...
