Answer:44.61 KJ
Explanation:
Let h_1,V_1,Z_1 be the initial specific enthalpy,velocity&elevation of the system
and h_2,V_2,Z_2 be the Final specific enthalpy,velocity&elevation of the system
mass(m)=7kg
Applying Steady Flow Energy Equation
![m\left [ h_1+\frac{v_1^2}{2g}+gZ_1\right ]](https://tex.z-dn.net/?f=m%5Cleft%20%5B%20h_1%2B%5Cfrac%7Bv_1%5E2%7D%7B2g%7D%2BgZ_1%5Cright%20%5D)
+Q=![\left [ h_2+\frac{v_2^2}{2g}+gZ_2\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%20h_2%2B%5Cfrac%7Bv_2%5E2%7D%7B2g%7D%2BgZ_2%5Cright%20%5D)

substituting values
![7\left [ h_1+\frac{13^{2}}{2g}+gZ_1\right ]+7\times2](https://tex.z-dn.net/?f=7%5Cleft%20%5B%20h_1%2B%5Cfrac%7B13%5E%7B2%7D%7D%7B2g%7D%2BgZ_1%5Cright%20%5D%2B7%5Ctimes2)
= ![\left [ h_2+\frac{23^2}{2g}+gZ_2\right ]](https://tex.z-dn.net/?f=%5Cleft%20%5B%20h_2%2B%5Cfrac%7B23%5E2%7D%7B2g%7D%2BgZ_2%5Cright%20%5D)
