The example of a subsystem and system relationship is option
A) mechanical toggle, Xbox controller
Explanation:
- Controls and Controllers are known as the mechanical, electro-mechanical, or electronic devices which are used to input signals to change the conditions or values which are in processes or access to buildings, operators, gated areas, etc.
- When you press and hold the given Shift button, these buttons which are chosen becomes an alternate inputs.
- Normally, there are three controllers(PID) which are used in any of the process industries inorder to maintain and control the required setpoint.
- an example of a subsystem and system relationship is a mechanical toggle, Xbox controller
- Controllers improve the steadiness and state of accuracy by decreasing the steady state error. When the steady state accuracy gets better, the stability also improves.
- Controllers are also used to help in reducing the unwanted offsets which are produced by the system.
Answer:
for a) F= 744.97 N
for a) F= 167.85 N
for a) F= 764.57 N
Explanation:
the pressure developed by the piston should be higher than the saturated vapor pressure of water for boiling point at T=120 to ensure boiling.
Then from steam tables
T= 120°C → P required=Pr= 198.67 kPa
then the pressure developed by the piston is
P = (m*g + F)/A
where m= mass of the piston ,g= gravity F= force required and A= area of the piston
then
Pr = P = (m*g + F)/A
F = Pr*A-m*g
since A= π/4*D²
F =π/4* Pr*D²-m*g
replacing values
F =π/4* Pr*D²-m*g = π/4*198.67 *10³Pa*(0.07m)² -2kg* 9.8m/s²
F= 744.97 N
b) for T₂=80°C → Pr₂=47.41 kPa
F₂ =π/4* Pr₂*D²-m*g = π/4*47.41*10³Pa*(0.07m)² -2kg* 9.8m/s²
F₂= 167.85 N
c) for m=0 (mass of the piston neglected) ,the force required is
F₃ =π/4*Pr*D² = π/4*198.67 *10³Pa*(0.07m)²= 764.57 N
F₃ =764.57 N
Answer:
This is not a clear indication of the hot zone as the information of the radioactivity of the background is not provided clearly.
Explanation:
According to IAEA as well as NRCP, the hot area is defined on the basis of the radioactivity reading it shows instead of contrast or comparative reading from the background. The value of radiation activity which will be required to declare an area as hot zone is if it is greater than 0.1 mSv/h or
.
Answer:
The solution code is written in C++.
- int main() {
-
- int a = 5;
- int b = 4;
-
- displayTwiceTheNumber(a);
- displayTwiceTheNumber(b);
-
- displayNumberPlusFive(a);
- displayNumberPlusFive(b);
-
- displayNumberSquared(a);
- displayNumberSquared(b);
-
- return 0;
- }
-
- void displayTwiceTheNumber(int num){
- cout << num * 2;
- }
-
- void displayNumberPlusFive(int num){
- cout << num + 5;
- }
-
- void displayNumberSquared(int num){
- cout << num * num;
- }
Explanation:
Firstly, create two integer variables, <em>a</em> and <em>b and </em>two sample values are assigned to the two variables, respectively (Line 3-4). Next, we pass the value of each variable <em>a</em> and <em>b</em> to the methods named <em>displayTwiceTheNumber(), displayNumberPlusFive(),</em> and <em>displayNumberSquared() </em>(Line 6- 13).
