Answer:
The ratio of the drag coefficients is approximately 0.0002
Step-by-step explanation:
The given Reynolds number of the model = The Reynolds number of the prototype
The drag coefficient of the model, = The drag coefficient of the prototype,
The medium of the test for the model, = The medium of the test for the prototype,
The drag force is given as follows;
We have;
Therefore;
= (1/17)^3 ≈ 0.0002
The ratio of the drag coefficients ≈ 0.0002.
Answer:
y = 5/2x - 5
Step-by-step explanation:
You have to rearrange the equation so that it is equal to y.
5x - 2y = 10
(5x - 2y) - 5x = -5x + 10
-2y = -5x + 10
(-2y)/-2 = (-5x)/-2 + (10)/-2
y = 5/2x - 5
Your answer is 94/15
if mixed, it’s 6 4/15
