Answer:
d) Is the thermal conductivity of the medium constant or variable.
Explanation:
As we know that
Heat equation with heat generation at unsteady state and with constant thermal conductivity given as
With out heat generation
In 2 -D with out heat generation with constant thermal conductivity
Given equation
So we can say that this is the case of with out heat generation ,unsteady state and with constant thermal conductivity.
So the option d is correct.
d) Is the thermal conductivity of the medium constant or variable.
Answer:
The head difference across the soil specimen is 39.29 cm and the discharge velocity is 0.02 cm/s
Explanation:
The head difference across the soil specimen is:
Where
k = hydraulic conductivity = 0.014 cm/s
Q = volume of water collected = 150 cm³/min = 2.5cm³/s
L = length of the soil specimen = 275 mm = 27.5 cm
A = area = 125 cm²
Replacing:
The hydraulic gradient is:
The discharge velocity is:
v = k*i = 0.014 * 1.43 = 0.02 cm/s
Answer:
Racking is the term used for when buildings tilt as their structural components are forced out of plumb. This is most commonly caused by wind forces exerting horizontal pressure, but it can also be caused by seismic stress, thermal expansion or contraction, and so on.
Explanation:
Answer:
a. WATER CONTENT.
mass of water (MW)= 417g - 225g
Mw= 192g
M= (Mw / Ms)
M= [192/417]
M= 0.46
M= 46.0%
b. Void Ration (e)
To calculate the void ratio we must first calculate the volume of solids. Then we can find the volume of voids by subtracting the volume of solids from the total volume.
Ps= (Ms/Vs)=GsPw
Therefore
Vs= (Ms/GsPw)
Vs= (417/ 2.70*1000)
Vs= 0.154cm3
But V= Vv+Vs
Vv=V-Vs
e= (Vv/Vs)
