Answer:
average velocity at the inlet = 3.66 m/s
Explanation:
given data
discharge Q = 25 ft³ /min = [tex]\frac{25}{60}[/tex] = 0.417 ft³
vacuum cleaner = 1 in by 5 in = [tex]\frac{1}{12} \ by\ \frac{5}{12}[/tex] 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 = [tex]\frac{0.417}{\frac{1}{12} \frac{5}{12} }[/tex]
average velocity at the inlet = 3.66 m/s
Answer:
The average velocity at the inlet is 3.66 m/s.
Explanation:
Given that,
Width = 1 in
Length = 5 in
Flow rate = 25 feet³/m
We need to calculate the average velocity at the inlet
Using formula of velocity at the inlet
[tex]v_{in}=\dfrac{Q}{A_{in}}[/tex]
Where, Q = flow rate
A = area
Put the value into the formula
[tex]v_{in}=\dfrac{\dfrac{25}{60}}{\dfrac{1}{12}\times\dfrac{5}{12}}[/tex]
[tex]v_{in}=12\ ft/s[/tex]
[tex]v_{in}=12\times0.3048[/tex]
[tex]v_{in}=3.66\ m/s[/tex]
Hence, The average velocity at the inlet is 3.66 m/s.
