Determine Δh - the difference in the height of the pistons in the communicating cylinders, if the cylinder diameters d1 = 30cm, d2 = 20cm. The piston loads are F1 = 120 kg, F1 = 20 kg, the absolute pressure in the closed left cylinder above the piston is p0 = 0 kg / cm2. Mercury γRT = 13.6 kg / dm3 is poured into the cylinders and connecting tubes.
