Answer:
Enthalpy at outlet=284.44 KJ
Explanation:
![m_1=1 Kg/s,m_2=1.5 Kg/s,m_3=22 Kg/s](https://tex.z-dn.net/?f=m_1%3D1%20Kg%2Fs%2Cm_2%3D1.5%20Kg%2Fs%2Cm_3%3D22%20Kg%2Fs)
![h_1=100 KJ/Kg,h_2=120 KJ/Kg,h_3=500 KJ/Kg](https://tex.z-dn.net/?f=h_1%3D100%20KJ%2FKg%2Ch_2%3D120%20KJ%2FKg%2Ch_3%3D500%20KJ%2FKg)
We need to Find enthalpy of outlet.
Lets take the outlet mass m and outlet enthalpy h.
So from mass conservation
![m_1+m_2+m_3=m](https://tex.z-dn.net/?f=m_1%2Bm_2%2Bm_3%3Dm)
m=1+1.5+2 Kg/s
m=4.5 Kg/s
Now from energy conservation
![m_1h_1+m_2h_2+m_3h_3=mh](https://tex.z-dn.net/?f=m_1h_1%2Bm_2h_2%2Bm_3h_3%3Dmh)
By putting the values
![1\times 100+1.5\times 120+2\times 500=4.5\times h](https://tex.z-dn.net/?f=1%5Ctimes%20100%2B1.5%5Ctimes%20120%2B2%5Ctimes%20500%3D4.5%5Ctimes%20h)
So h=284.44 KJ
Answer:
γ
=0.01, P=248 kN
Explanation:
Given Data:
displacement = 2mm ;
height = 200mm ;
l = 400mm ;
w = 100 ;
G = 620 MPa = 620 N//mm²; 1MPa = 1N//mm²
a. Average Shear Strain:
The average shear strain can be determined by dividing the total displacement of plate by height
γ
= displacement / total height
= 2/200 = 0.01
b. Force P on upper plate:
Now, as we know that force per unit area equals to stress
τ = P/A
Also, τ = Gγ![_{xy}](https://tex.z-dn.net/?f=_%7Bxy%7D)
By comapring both equations, we get
P/A = Gγ
------------ eq(1)
First we need to calculate total area,
A = l*w = 400 * 100= 4*10^4mm²
By putting the values in equation 1, we get
P/40000 = 620 * 0.01
P = 248000 N or 2.48 *10^5 N or 248 kN
