Pressure at the highest point

  1. Aug 12, 2017 #1
    1. The problem statement, all variables and given/known data
    Considering the figure. The liquid has a density $$\rho$$. What is the pressure at B?

    3. The attempt at a solution
    In a solution that I have found on internet, it is said that the pressure in B is $$p_0 - \rho g (h_1 + d+h_2 )$$. How is it possible? I thought that the pressure at B was $$p_0 + \rho g (-h_1)$$

    That would be true in a static arrangement, but the fluid is moving. Try Bernoulli's equation.
