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

--------- --------

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
