) A watershed experiences a rainfall of 8 inches. What is the runoff volume when the curve number is 80

finlep [7]

Answer:

5.625 inches

Step-by-step explanation:

Given that:

Total Rainfall in inches (P) = 8 inches

The runoff volume (in inches) Q = ???

The curve number CN = 80

Recall that: The runoff volume can be calculated by using the formula:

$Q = \dfrac{(P-0.2S)^2}{(P+0.8S)}$ for P > 0.2S

Q = 0 for P < 0.2S

$S = \dfrac{1000}{CN}-10$

where:

curve number CN = 80

$S = \dfrac{1000}{80}-10$

S = 2.5 inches

Since the rainfall (P) is greater than 0.25

Then:

$Q = \dfrac{(P-0.2S)^2}{(P+0.8S)}$

$Q = \dfrac{(8-0.2(2.5))^2}{(8+0.8(2.5))}$

$Q = \dfrac{(8-0.5)^2}{(8+2)}$

$Q = \dfrac{(7.5)^2}{(10)}$

$Q = \dfrac{(56.25)}{(10)}$

Q = 5.625 inches

Thus, the runoff volume = 5.625 inches

What should be added to (-5 a2b - 9 ab) to get a2b + 3 ab?

Doss [256]

Based on given conditions,

$a²b + 3 ab - (-5 a²b - 9 ab)$

$→a²b + 3 ab + 5 a²b + 9 ab$

$→(a²b + 5 a²b) + (3ab + 9 ab$

Now collecting the coefficients and adding them,

$(1 + 5)a²b + (3 + 9)ab$

$→6 {a}^{2}b + 12ab$

Hence, the 6a²b + 12ab should be added.
