Answer:
the percent increase in the velocity of air as it flows through the dryer is 12%
Explanation:
given data
density of air ρ = 1.18 kg/m³
density of air ρ' = 1.05 kg/m³
solution
we know there is only one inlet and exit
so
ρ × A × v = ρ' × A × v' ........................1
put here value and we get
= 1.12
so the percent increase in the velocity of air as it flows through the dryer is 12%
Answer:
The answer is 2217.32m³
Explanation:
Given that:
V₂ = (15 + 5/2) * 3 * 100 = 3000 m³
r₁ = 21.7kN/m3
w (water) = 11.4%.
e₂ (void ratio) = 0.47
V₁ = ?
Now,
rd₁ = r₁/1 + w₁ = 21.7/1 +(11.4/100)
= 19.47 kN/m3
Thus,
rd₂ = r₁/1 + e₂ = 21.7/1+ 0.47 = 14.76 kN/m3
Then,
V₁/V₂ = rd₁/ rd₂
V₁ = 3000 * 14.76/19.97
V₁ = 2217.32m³
Therefore, volume that should be excavated from the borrow pit is 2217.32m³
