can i use Bernoullies equation

svenki7

I want to solve the
In the pipe( Image) at Point 1 velocity and diameter constant( V1, d1). At point 2, i want change diameter 0 to complete close (complete open to complete close i.e dia= d1 to dia=0).
It is like Orifice at point 2 (here diameter change d1 to 0 at point 2).
how can i solve this problem, velocity at point 2 in terms of diameter. I had solve this problem by Bernoullies equation at last i got zero.

guys can you help me plz !!!
