A vortex tube has an air inlet flow at 20 degrees Celsius, 200 kPa and two exit flows of 100 kPa, one at 0 degrees celsius and the other at 40 degrees Celsius. The tube has no external heat transfer and no koving parts, hence no work and all the flows are steady and have negligible kinetic energy. Find the fraction of the inlet flow that comes out at 0 degrees Celsius.
