Civil gate questions

At two points 1 and 2 in a pipeline the velocities are V and 2V, respectively. Both the points are at the same elevation. Both the points are at the same elevation. The fluid density is ρ. The flow can be assumed to be in compressible, inviscid, steady and irrotational. The difference in pressures P1 and P2 at points 1 and 2 is
(A) 0.5ρV2
(B) 1.5ρV2
(C) 2ρV2
(D) 3ρV2
