- A typical differential manometer is attached to two sections A and B in a horizontal pipe through which water is flowing at a steady rate as shown in Figure 4. The deflection of mercury in the manometer is 0.60 m. Calculate the difference in pressure between sections Aand B. Take the densities of water and mercury as 1000 kg/m3 and 13570 kg/m3 respectively.arrow_forwardA manometer is a device that measures pressure. A common simple manometer consists of a U shaped tube of glass filled with some liquid. Water is first filled into the U-tube until a clear horizontal water surface is visible on both legs of the U-tube. Unequal amounts of kerosene were then dropped into both legs of the U-tube. The height of kerosene in the left leg was measured as 8.3 cm high and 5.2 cm on the right leg. The difference in elevation between the interfaces of kerosene and water measured 2.5 cm. Determine the specific gravity of kerosene.arrow_forwardA mercury Manometer is attached to a pipe having suction pressure.
