Answer:
theres 60 minutes in an hour
Step-by-step explanation:
hypotenuse = adjacent / cos x
h = 4 / cos(59)
h = 7.76641610 ...
CD=8
Answer:
V = 20.2969 mm^3 @ t = 10
r = 1.692 mm @ t = 10
Step-by-step explanation:
The solution to the first order ordinary differential equation:
Using Euler's method
Where initial droplet volume is:
Hence, the iterative solution will be as next:
- i = 1, ti = 0, Vi = 65.45
- i = 2, ti = 0.5, Vi = 63.88
- i = 3, ti = 1, Vi = 62.33
We compute the next iterations in MATLAB (see attachment)
Volume @ t = 10 is = 20.2969
The droplet radius at t=10 mins
The average change of droplet radius with time is:
Δr/Δt =
The value of the evaporation rate is close the value of k = 0.08 mm/min
Hence, the results are accurate and consistent!
You have to use the Law of Sines to find K. But indirectly, since you haven't got an angle measure for K or a side measure of k. We have to find J and then use the Triangle Angle-sum theorem to find K.
. Solve for J to get J = 35.1. 180 - 102 - 35.1 = 42.9 so K is 42.9
