Answer:
A)
B)
Explanation:
Given data:
P-1 = 100 lbf/in^2
degree f
effeciency = 80%
from steady flow enerfy equation
where h1 and h2 are inlet and exit enthalpy
for P1 = 100 lbf/in^2 and T1 = 500 degree F
for P1 = 40 lbf/in^2
exit enthalapy h_2
from above equation
[1 Btu/lbm = 25037 ft^2/s^2]
b) amount of entropy
at
B - they most certainly are responsible
Answer:
18 teeth/inch
Explanation:
Given that: i. driver gear has 8 teeth and diametral pitch of 6 teeth/inch.
ii. follower gear has 24 teeth.
Let the followers diametral pitch be represented by x.
Then,
8 teeth ⇒ 6 teeth/inch
24 teeth ⇒ x teeth/inch
So that;
x =
=
= 18 teeth/inch
The diametral is 18 teeth/inch
Answer:
output=
Explanation:
output =transfer function ×input
here transfer function G=
input = unit impulse
in S domain unit impulse =1
so output =
=
Answer:
b. The universe may continue to expand.
Explanation:
The most supported theory about the future of the universe is that, it may continue to expand up to such point that it will become too cold to allow any forms of life to pull through. This is popularly known as the "Big Freeze."
Such acceleration of expansion is caused by the so-called, "dark energy." This also explains why the <u>acceleration of expansion is not constant</u>. This thereby causes the distance between galaxies to <em>grow farther apart.</em>
