Answer:
Angle of discharge make at the edge of tube=64.9 degrees.
Answer:
Output voltage equation is 
Explanation:
Given:
dc gain
dB
Input signal 
Now convert gain,

DC gain at frequency
is given by,



At zero frequency above equation is written as,


Now we write output voltage as input voltage,

Therefore, output voltage equation is 
Answer:
a. 0.9263
b. 0.4872
c. 13.83kN/m
Explanation:
moisture content (ω) = 0.32
void ratio (e) = 0.95
specific gravity (
) = 2.75
the degree of satruation (S) =
=0.32×2.75/0.95 = 0.9263
b. porosity (n) =
= 0.95/(0.95 + 1)= 0.4872
c. dry unit weight (γ
) = 
taking specific unit weight of water (V
)= 9.81kN/m
γ
= 2.75 × 1000/(1 + 0.95) = 13.83kN/m
