Task 38 Determine the readings of h

Task 38 Determine the readings h of a two-fluid differential pressure gauge, in which a system of two pistons having a common rod will be in equilibrium if there is liquid A in both cylinders, liquid B in the knee of a two–fluid differential pressure gauge, the absolute pressure shown by a spring pressure gauge is Rm = 0.9 atm. The friction of the pistons is neglected
