Extracted text: Water with density Pwater = 1000 kg/m³, is transported in 30° circular pipe, inclined at an angle of 30°, relative to the horizontal plane. The readings of the connected liquid manometer, as shown on the figure, is h = 12 cm. The manometric fluid used is a mercury with density Pmercury = 13600 kg/m³. The temperature of both fluids is equal and is t = 20 °C. Find the pressure difference Ap = p, – p, in the both cross- h sections 1 and 2. ****
