Answer:
average velocity at the inlet = 3.66 m/s
Explanation:
given data
discharge Q = 25 ft³
/min = = 0.417 ft³
vacuum cleaner = 1 in by 5 in = ft
solution
we know discharge that is express as
Q = Area × Velocity .............1
put here value and we will get average velocity at the inlet
average velocity at the inlet =
average velocity at the inlet = 3.66 m/s
