1. FIGURE Q1 shows an inverted U-tube manometer containing Fluid C. Assuming specific gravity of Fluid C ranging between 0.85 1.00, determine the pressure difference between two points in a pipe. If the pressure at one point is reduced by 2.5 kPa, evaluate the changes of the levels of Fluid C in the manometer. State ALL assumptions. 45 cm Fluid C 23 cm Fluid C Pipe A Pipe B FIGURE Q1 [30 marks)
