Answer:
160 W
Explanation:
The relation is ...
Real Power = (pf)(V)(A)
= 0.8(100)(2) = 160 . . . . watts
Answer:

Explanation:
We can assume that the general formula for the drag force is given by:

And we can see that is proportional to the area. On this case we can calculate the area with the product of the width and the height. And we can express the grad force like this:

Where w is the width and h the height.
The last formula is without consider the area of the carrier, but if we use the area for the carrier we got:

If we want to find the additional power added with the carrier we just need to take the difference between the multiplication of drag force by the velocity (assuming equal velocities for both cases) of the two cases, and we got:

We can assume the same drag coeeficient
and we got:


1.7 ft =0.518 m
60 mph = 26.822 m/s
In order to find the drag coeffcient we ned to estimate the Reynolds number first like this:

And the value for the kinematic vicosity was obtained from the table of physical properties of the air under standard conditions.
Now we can find the aspect ratio like this:

And we can estimate the calue of
from a figure.
And we can calculate the power difference like this:

Answer:
a)True
Explanation:
Rolling:
Rolling is a metal forming in which a material passes through two or more than two depends on conditions,rolls to produce the desired product.
Ring rolling:
In ring rolling a thick ring compresses by rolls to produce the large diameter ring.Actually volume of material is constant so when diameter of ring increases then to compensate it, the thickness of ring reduces .In simple words we can say that in ring rolling a thick ring of smaller is rolled into a thin ring of larger diameter.
