Bernoulli's equation is given by;

Energy per unit volume at point 1 = Energy per unit volume at point 2 = c.
Energy per unit volume at any point = c.
Pressure energy + potential energy per unit volume + Kinetic energy per unit volume = c.
P + ρgz + (1/2)ρ.v^2 = c.
P/ρ + gz + (1/2)v^2 = c.
Now differentiating the above equation.

dP/ρ + v.dv + g.dz = c.

pressure energy+kinetic energy+potential energy = const(newtons law by eliminating C.F ,S.T,V.F).

PV+(1/2)Mv^2+Mgh = c.

By diff it we get answer.

Bernoulli's equation is:

P/ρ + V^2/2 + g*Z. Just differentiate it.
