Answer:
The electrical power is 96.5 W/m^2
Explanation:
The energy balance is:
Ein-Eout=0

if:
Gsky=oTsky^4
Eb=oTs^4
qc=h(Ts-Tα)


if Gl≈El(l,5800)

lt= 2*5800=11600 um-K, at this value, F=0.941

The hemispherical emissivity is equal to:

lt=2*333=666 K, at this value, F=0

The hemispherical absorptivity is equal to:

Annual Payment where F is accumulated sum of amount, n is number of years and i is annual rate of interest. The standard notation equation is in the image since i can’t type it-
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
