I will write a program about principle bernoulli, but i have a problem.
My input data:
Pressure(p1) = 1000
Cross-section(A1) = 1
Velocity(V1) = 1
Cross-section(A2) = 0.5
Velocity(v2)= (V1A1)/A2
to simplify: h1=h2
i'm counting the pressure p2 : p2 = p1 + 0.5*v1*v1 - 0.5*v2*v2 , so i getting negative pressure..
This is a problem (negative pressure)
I'm trying to add atmospheric pressure, but it doesn't solve my problem.
Is a mathematical formula is good? Is there any other relationship?
