Q = 1/2 nv2

SAT
1 answer:
ArbitrLikvidat [17]4 years ago
6 0

Answer:

<em>2.25 or 9/4.</em>

Explanation:

To solve this problem, you need to set up to equations with variables. Let q1 be the dynamic pressure of the slower fluid moving with velocity v1, and let q2 be the dynamic pressure of the faster fluid moving with velocity v2. Then,

v2 = 1.5v1

Given the equation q =  1 /2

nv2, substituting the dynamic pressure and velocity of the faster fluid gives q2 = 1 /2  n(v2)^2. Since v2 = 1.5v1, the expression 1.5v1 can be substituted for v2 in this equation, giving q2 =  1 /2  n(1.5v1)^2. By squaring 1.5, you can rewrite the previous equation as:

q2 = (2.25)( 1 /2 ) n(v1)^2=(2.25)q1

Therefore, the ratio of the dynamic pressure of the faster fluid is

q2 /q1  =  2.25q1 /q1  = 2.25

<em>The final answer is 2.25 or 9/4.</em>

yKpoI14uk [10]
I would have to say gathering information since she’s gathering information about the training programs.
Weighing the pros and cons would be listing the good things and bad things about this job.
If she is reflecting, she is thinking about her decision.
She is not taking action since she is only researching, she has not actually started the job.

Hope this helps :)
