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:
type 2, k = 4
Explanation:
(a) The transfer function of the controller for a satellite attitude control is
The transfer function of unity feedback structure is
To determine system type for reference tracking, identify the number of poles at origin in the open-loop transfer function.
For unity feedback system, the open-bop transfer function
Determine the poles in G(s)4(s).
s = 0,0,-5
Type of he system is decided by the number of poles at origin in the open loop transfer function.
Since, there are two poles at origin, the type of the system will be 2.
Therefore, the system type is
Type 2

Explanation:
Tolerance equals the difference between lower and upper limit dimensions. Example; for 0.500-0.506 inch the tolerance would be 0.006 inch. BILATERAL TOLERANCE : It is a way to express tolerance by using both minus and plus variations from a given size.
