Dont know if this is the right forum but here goes
In a pipe with a diameter 0.15 there is a smaller area with the diameter 0.075

l l
--------- --------
A 0.15 B 0.075
The speed of the fluid at point A is 1m/s
the statik pressure in the pipe is 1 Bar at point A
waters density is 1000 kg/m^3
I know the dynamik pressure is 500Pa at point A
I need to find the statick pressure after point B
I use Bernoullis formula
i dont know were the sign for row is on my cpu so i will use @
@*C^2/2+@*g*h+P1=@*c^2/2+@*g*h+P2
I know i can cross out @*g*h
Anyways this is as far as i got could somone please check my work
P2=500+100000-(1000*(2^2/2)) unsure if it is 2^2/2
= 98500pa
Also sorry for the spelling am swedish
