Minor losses due to sudden expansion By bernoulli's eq.
h=(v1^ 2-v2^2/2g)-(p1-p2/$g).
And by momentum eq,
(p1-p2/$g)=v2(v2-v1)/g and put the value in above eq,
Then,
h=(v1-v2)^2/2g.
h=(v1^ 2-v2^2/2g)-(p1-p2/$g).
And by momentum eq,
(p1-p2/$g)=v2(v2-v1)/g and put the value in above eq,
Then,
h=(v1-v2)^2/2g.

I Think that Answer is D.
Becoz according to Bernoulli's Equation.
H = P1/wg-p2/wg = (v1^2-v2^2)/2g.
Becoz according to Bernoulli's Equation.
H = P1/wg-p2/wg = (v1^2-v2^2)/2g.
