Problem 4: Consider the system of four compartments shown in the figure. Each compartment in connected to the nearby compartments with mercury-filled glass manometers (shown in blue, with the density of mercury being 13.5 g/cm³). The compartments are ordered by increasing pressure from left to right and are stationary at ground level. The height difference in the mercury between compartments A and B is 13.9 cm, and between C and D is 6.3 cm. A H₁ H₂ H3 Rectanga Otheexpertta.com Part (a) If the pressure is measured in compartment C at Pc 1.47 atm and compartment A is open to the atmosphere, what manometer reading, in cm, should be found between B and C? Numeric A numeric value is expected and not an expression. H2= Part (b) What is the pressure in compartment D, in atm? Numeric PD,abs= A numeric value is expected and not an expression. Part (c) If we were to add an additional manometer between compartments B and D (in addition to comparent C), what height difference would we find in centimeters? Numeric H4= A numeric value is expected and not an expression.
