In the following pipe, water is flowing from point A to point B. The darker fluid has a specific gravity of 1.25, which means its specific weight is 1.25 times the specific weight of water at 4°C and 1 atm. The lighter fluid is water at 60°C, with a specific weight of 9.65 kN/m³. To calculate the pressure difference between A and B, you can use the equation p_A + gamma_dark(1.18 m) + gamma_water(0.46 m) = p_B. However, there is a little extra space between the fluids that is not being considered and you have no information about the remaining height. How would this affect the calculation? Also, What would be the effect of the pipe not being in a vertical position? Consider two cases: inclination between 0 and 90 degrees, and completely horizontal.
