A = cross sectional area of the pipe. When the pressure is expressed in terms of the equivalent height of a column of that fluid, as is common with water, the friction loss is expressed as S, the "head loss" per length of pipe, a dimensionless quantity also known as the hydraulic slope.
Answer:
2/9
Step-by-step explanation:
2/6 × 2/3 = 4/18= 2/9
Answer:
63
Step-by-step explanation:
Each term in a geometric sequence progresses by multiplying a constant (let us name it <u>r</u>).
Let us<u> solve for this constant</u> r in order to find the 13th term.
If the seventh term is 7, the tenth term would be 7*r*r*r, or . We also happen to know that the 10th term is 21. Let us make a <u>new equation</u>:
or, approx. 1.442249570307408
Using the same logic, the 13th term would be 7*r*r*r*r*r*r, or . We may now <u>substitute</u> what we know, r, into this expression to obtain the 13th term:
Therefore, the 13th term of this progression is 63.

Answer:
9
Step-by-step explanation:
First you put in b, which would look like this: 4(1/4+2)
Then you could do it two ways, you can use distributive property, or just add within the parenthisis.
Distributive Property:
it would be 4* 1/4, which is one, and add 4*2, which is nine.
Parenthesis:
just add 2 and 1/4, which is 2 1/4. 2 1/4 is equal to 9/4, and that times 4 is nine.
Hope it helps!
