Hot air flow in pipe
Hot air flow in pipe
(OP)
The problem that I am working on is to figure out the characteristics of flow in a pipe.
Air: 1500F, 200lb/min,100psi.
I have solved for velocity when given a pipe diameter of 4". I have solved for reynolds no.
I have a velocity of about 1200ft/s. Reynolds no = 2650265. So no matter what the flow will be turbulent with a realistic pipe size...
Can someone verify my numbers? Do I need to approach this differently due to hot air temp and higher pressure?

RE: Hot air flow in pipe
At a velocity of 1200 ft/sec in a 4" pipe, but only 100 psi, your pipe won't be very long. Exit losses and how the gas exits the pipe will have a significant effect on pressure and flow characteristics. Maybe try a similar question in the aeronautical section?

I see that the flow is more than sonic but there's no diverging nozzle until the inlet of the turbine housing.
What kind of effects or things to solve for in this system?
