from continuity equation we can write as 
![P_1-P_2=\frac{\rho }{2}\left [ v_2^2-v_1^2\right ]](/tpl/images/0458/5391/b9f0a.png)
![P_1-P_2=\frac{\rho }{2}\left [ v_2^2-(\frac{A_2}{A_1})^2v_1^2\right ]](/tpl/images/0458/5391/a5926.png)
![(31-25)\times 10^3=\frac{10^3}{2}\left [ v_2^2-(0.3599)^2v_2^2\right ]](/tpl/images/0458/5391/5a6b0.png)
![6\times 2=v_2^2=\left [ 1-0.359^2\right ]](/tpl/images/0458/5391/c5fdb.png)
