Yes, 550mm is the pressure head at B.

Use the following:

 

pB + (1/2)*rho*vB^2 = pA + (1/2)*rho*vA^2                   pB = rho*g*h

 

vA*AreaA =  vB*AreaB

 

pB + (1/2)*rho*vB^2  =  pC + (1/2)*rho*vC^2  + (0.15/2)*rho*vB^2

.

vC*AreaC = vB*AreaB

 

Volume flow rate = v*Area

 

v is velocity,  p is static pressure

.

Pressure head = p/(rho*g)

Yes Alan, I applied the energy equation, but my question was about h = 550 mm is it the pressure head at B? 

 

And this is how i solve it, maybe its not clear!
