Question

Fluid 1 is water ( = 1000 kg/m3) and is travelling through the piping system shown, represented by the circular sections of pipe at A and B running in and out of the page. Fluid 2 is mercury ( = 13550 kg/m3). Determine the pressure difference between points A and B when h1 = 0.6 m, h2 = 0.15 m, h3 = 0.2 m and g = 9.81 m/s2.
