Answer:

V_2=6.17\ m/s

Q=0.49\ m^3/s

Explanation:

Given that

A_1=0.03m^2

A_2=0.08m^2

We know that from continuity equation

Q=A_1V_1=A_2V_2

So

A_1V_1=A_2V_2

0.3V_1=0.08V_2

V_1=2.66V_2

Now from energy equation

P_1+\dfrac{1}{2}\rho V_1^2=P_2+\dfrac{1}{2}\rho V_2^2

P_2-P_1=\dfrac{1}{2}\rho V_1^2-\dfrac{1}{2}\rho V_2^2

140=\dfrac{1}{2}\times 1.2\times 7.11\times V_2^2-\dfrac{1}{2}\times 1.2\times V_2^2

V_2=6.17\ m/s

Q=A_2V_2

Q=6.17 x 0.08

Q=0.49\ m^3/s
