Answer:
The effective overall heat transfer coefficient for the combination,
Explanation:
According to the question, the total area includes the areas of the wall, window and door.
Total area, A = 100 * 10 = 1000 ft²
Area of the window,
Area of the door,
Area of the wall,
<u>Heat transfer coefficients:</u>
For wall,
For window,
For door,
To get the overall heat - transfer coefficient for the combination:
Answer:
Minimum area of rectangle = 24 cm²
Explanation:
Given:
Length of rectangle = 6 cm
Width of rectangle = 4 cm
Find:
Minimum area of rectangle
Computation:
Area of rectangle = Length of rectangle x Width of rectangle
Minimum area of rectangle = Length of rectangle x Width of rectangle
Minimum area of rectangle = 6 x 4
Minimum area of rectangle = 24 cm²
Answer:
the MTTF of the transceiver is 50.17
Explanation:
Given the data in the question;
failure modes = 0.1 failure per hour
system reliability = 0.85
mission time = 5 hours
Now, we know that the reliability equation for this situation is;
R(t) = [ 1 - ( 1 - )³]
so we substitute
R(5) = [ 1 - ( 1 - )³] = 0.85
[ 1 - ( 1 - )³] = 0.85
[ 1 - ( 0.393469 )³] = 0.85
[ 1 - 0.06091 ] = 0.85
0.9391 = 0.85
= 0.85 / 0.9391
= 0.90512
MTTF = 5 / -ln( 0.90512 )
MTTF = 50.17
Therefore, the MTTF of the transceiver is 50.17
