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

Explanation:
ADT for an 2-D array:
struct array{
int arr[10];
}arrmain[10];
An application that stores an array with 1000 rows and 1000 columns, where less than 10,000 of the array values are non-zero. The two different implementations for such arrays that would be more space efficient than a standard two-dimensional array implementation requiring one million positions are :
1) struct array{
int *p;
}arr[1000];
2) struct array{
int *p;
}arr[1000];
