3.Conclusion
Steady-state
potential energy & non-flow work are negligible
Continuity Eq.
Analysis
△P doesn’t change nearly
When (A₂/A₁) is smaller than 0.1.
☞ Even though (A₂/A₁) is smaller than 0.1,
actual effect is not remarkable.
Pressure inside fan : 101325-599=100726Pa
Inside pressure is lower than atmosphere
Air flows into inside
