A multifluid manometer is used to measure the pressure of paraformaldehyde in the pipe. All the fluids inside the manometer are assumed to be totally immiscible with each other. P3 = 63.27 kPa 3 Heptane (SG = 0.684) Pgauge =? 6 cm Paraformaldehyde (SG = 0.88) Air- 13 cm Pipe Ppipe =? 16 cm 9 cm 5) cm Acetonitrile (SG = 0.786) Dimethyl sulfoxide (SG = 1.1) (a) Determine the density of acetonitrile (Ace), heptane (Hept), dimethyl sulfoxide (DMSO), and paraformaldehyde (Par). [4 marks] (b) Calculate the pressure a points 1, 2, and 4. [9 marks] (c) Calculate the value of unknown height labelled x" cm if the pressure difference between [4 marks] gauge pressure and pressure at the midpoint of the pipe is 1029.46 Pa. [3 marks] (d) Calculate the pressure at points 5 and 6.
