(d) Water flows in two different horizontal pipes having a height difference of 55cm. A U- tube manometer is connected across the two pipes to measure the pressure difference between two points A and B shown in Figure 1. The manometer reading is 25cm when using a mercury as a manometric fluid. Determine the (i) static pressure difference between the water in the two pipes. (ii) manometer reading if a manometric fluid of density 2500 kg/m³ is used instead of mercury.
