Answer:
Its specific resistance will be around 0.015
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
Answer:
True Strain at failure = 1.386
Explanation:
For the question, ductility is given in reduction In the area to be 0.75
Let the initial Cross sectional Area of wire be Ao
And the final cross sectional Area of wire of cross sectional Area of wire at fracture be A
(Ao - A)/Ao = ductility = 0.75
Ao - A = 0.75Ao
A = Ao - 0.75Ao
A = 0.25 Ao
True Strain = In (Lf/Lo)
To obtain the ratio of the lengths of wire,
The volume of the wire stays constant, that is, Vo = Vf; Vo = Ao × Lo and Vf = A × Lf
AoLo = ALf
Lf/Lo = Ao/A
In (Lf/Lo) = In (Ao/A) = In (Ao/0.25Ao) = In 4 = 1.386
True Strain = 1.386

Answer:

So, Ma < 1 Flow is Subsonic
Explanation:
Mach Number:
Mach Number is the ratio of speed of the object to the speed of the sound. It is used to categorize the speed of the object on the basis of mach number as sonic, supersonic and hyper sonic. (It is a unit less quantity)
Mach < 1 Subsonic
Mach > 1 Supersonic
Ma= Speed of the object/Speed of the sound

So, Ma < 1 Flow is Subsonic
