Q.3 A differential manometer is used to measure pressure difference between two fluid systems. Two parallel pipes carrying freshwater and seawater are connected to each other by a double u-tube differential manometer as shown in figure. Determine pressure difference between the two pipelines if h= R cm (where Ris your roll number). Also if the pressure difference between the pipes is doubled, what will be the difference in heights(h) of mercury? Take density of sea water at that location to be 1035kg/m and the specific gravity of the oil is 0.72. Assume all fluids are incompressible.
