If you suspect anything is wrong with it such as it not working or before using one of them
Answer:
Explanation:
Part c:
(Q)out = m(u1 - u2) = 5(2506-193.67) = 11562KJ
Total Entropy change = Δs + (Qout/Tsurrounding) = -33.36 + (11562/393) = 5.44KJ/K
Answer:
Explanation:
a) - Taking enthalpy from the ideal air structure that is :
Given,
Then, we have to apply the equation of the energy rate balance.
After applying that we have:
Then, we have to put values in the equation.
b) - Here, we have to apply the equation of the continuity.
Then, we have to put values in the equation.
Then, the values are :
and,
Then, we have to put values in the equation.
Answer:
Attached is the logic diagram.
Explanation:
Motion Sensors S1 S1 S3 S4
Master switch M
Siren Enable Switch A
Light Enable Switch L
Phone Call Enable Switch P
Buzzing Siren B
Flashing Light F
Call Box C
The logic operates as follows, when ANY of the sensors goes active (1), the output must be active, so for the sensors inputs we use an OR gate. After that the OR signal output goes to the switches AND gates, if any of the switches is off, the outputs are going to be LOW or (0)
