Applying Bernoulli's equation P1+ρgh1+21ρv12=P2+ρgh2+21ρv22 [h1&h2 are height of point from any reference level] Given V1=V2=0 (for statement-1) ∴P1−P2=g(h2−h2)
For statement-2 P1+21ρv12=P2+21ρv22 $\begin{aligned}
& P_1-P_2=\rho g h \
& P_1-P_2=\frac{1}{2} \rho v_2^2-\frac{1}{2} \rho v_1^2 \
& \rho g h=\frac{1}{2} \rho v_2^2-\frac{1}{2} \rho v_1^2 \
& 2 g h=v_2^2-v_1^2
\end{aligned}$
