Question

what is the pressure at the in-gate system will be maximum at the gating system?

Answer 1

OK The answer would  be 1:2:4.

As we know, as the area increases velocity decreases (A1V1=A2V2).

So, from bernoulli's principle when velocity decreases pressure increases.

Basically, when area increases pressure will increase.

Answer 2

Answer:

but given Ans is 4:8:3 as per previous year solved book
