Answer:
D. a triangle and a T-Square
Explanation:
A T-Square is the best drawing tool to create squares. You would need a squares to create cubes.
To solve the problem it is necessary to take into account the concepts related to the Reynolds Number and the Force of drag on the bodies subjected to a Fluid.
The Reynolds number for the Prototype and the Model must therefore be preserved,
Re-arrange for the speed of the model we have,
Our values at 20°C would be given of the table of Physical Properties of water where
While for the values previous given we have
And we have a Ratio between the prototype and the model of 16:1, then
PART B) To calculate the ratio of the drag force now we have to,
Replacing with our values we have,
Therefore the ratio of drag force for prototype and model is 0.5016
Answer:
Detailed solution is given in the attached diagram
Answer:
0.59
Explanation:
based on Lever's phase rule, we can find the fraction of the α phase in the structure using the following formula:
where
= mass fraction of element B in the entire alloy or mixture = 40%
= mass fraction of element B in the β phase = 90%
= mass fraction of element B in the α phase = 5%
hence we have
∴ The fraction α phase in the structure is ≈ 0.59
