my project is like Simulating Thermal Comfort In a Ventilated Office Space - YouTube
at 2:13- velocity inlet
Original: i type 2m/s +z-axis
Now
I want to add an angle of the air inlet, tilt-up 30degree
So i decompose it into 1.73m/s +z-axis plus 1m/s +x-axis, by Pythagorean Theorem
To keep the airflow(CMH) constant, is it the correct way to do?
