To solve the problem it is necessary to use the concepts related to frictional dissipation per unit mass, energy balance equation and Volumetric flow rate.
The frictional dissipation per unit mass is defined as
Where,
Superficial velocity of fluid
Fluid viscoisty
Porosity
Fluid density
L = Packed bed length
= Effective particle diameter
Through energy balance equation we have that
Neglect the change in velocity and pressure and the work done we have,
We have also that de grade is defined as
With our values and replacing at the previous equation we have,
Previously with the given depth and height we have to
Therefore the Volumetric flow rate,
Therefore the desired volumetric flow rate is 2456gal/min
Let “w” and “L” be the width and length of the rectangle. “p” and “a” are perimeter and area
For python,
w=int(input(“width”))
l=int(input(“length”))
a= w*l
p=2*w+2*l
print(str(a), str(p)
Remove whatever is holding the old filter in place and remove it. Put the new filter on in the same position as the old filter. Replace whatever holds the filter in place, and make sure it's secure. Replace the fuse for the fuel pump in the fuse box.
Answer:
t=13.49 min
Explanation:
Given that
I=300 A
A= 0.21 cm²
L= 0.85 m
Number of charge carriers per unit volume = 8.49 x 10²⁸ m⁻³.
We know speed of the electron given as
V=J/ne
J= I/A
So
V=I/neA
V=0.00105 m/s
lets take t is the time when electron travels from car battery to the starting motor
t = L/V
t=809.52 s
t=13.49 min
