Answer:
The solution for the given problem is done below.
Explanation:
M1 = 2.0
= 0.3636
= 0.5289
= 0.7934
Isentropic Flow Chart: M1 = 2.0 ,
= 1.8
T1 =
(1.8)(288K) = 653.4 K.
In order to choke the flow at the exit (M2=1), the above T0* must be stagnation temperature at the exit.
At the inlet,
T02=
= (1.8)(288K) = 518.4 K.
Q= Cp(T02-T01) =
= 135.7*
J/Kg.
Answer:
Rubber:Covalent bonding
Barium sulfide:ionic bonding
Solid xenon: Van daar Waal bond.
Bronze:Metallic bond
Nylon:Covalent bonding
Aluminum phosphate: mixture of ionic and covalent bond
Explanation:
Rubber is mainly composed of isoprene which is predominantly covalent bond
Barium sulphide is predominantly ionic bonding
Is xenon is inert its bond is van daar Waal
Bronze is an alloy of metal usually held by metallic boding
Nylon:covalent bonding
Aluminium phosphate have a mixture of covalent and ionic bond
Answer:
type 2, k = 4
Explanation:
(a) The transfer function of the controller for a satellite attitude control is
![G = \frac{1}{s^2}](https://tex.z-dn.net/?f=G%20%3D%20%5Cfrac%7B1%7D%7Bs%5E2%7D)
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
![G(s)D_c(s)=\frac{1}{s^2}\frac{10(s+2)}{s+5}](https://tex.z-dn.net/?f=G%28s%29D_c%28s%29%3D%5Cfrac%7B1%7D%7Bs%5E2%7D%5Cfrac%7B10%28s%2B2%29%7D%7Bs%2B5%7D)
![=\frac{10(s+2)}{s^2(s+5)}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B10%28s%2B2%29%7D%7Bs%5E2%28s%2B5%29%7D)
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
