Water (p = 1000 kg/m³) enters the piping system shown below through section 1 at a volume flow rate of 0.03 m³/s and pressure of P₁ = 2 × 105 Pa (gage) and exits through sections 2 and 3 (at unknown pressures). The mercury (p = 13,550 kg/m³) U-tube manometer shown is used to measure the flow rate through section 2 and reads h = 13 cm. The pipe lengths shown in the figure are a = 0.5 m, b = 2.0 m, and c = 0.5 m. All pipes in the figure have diameter D = 7 cm. Neglecting frictional losses in the pipes and fittings: (a) Determine the volume flow rate through section 2. (b) Calculate the gage pressure at point A.

Transcribed Image Text:Water (p = 1000 kg/m³) enters the piping system shown below through section 1 at a volume
flow rate of 0.03 m³/s and pressure of P₁ = 2 x 105 Pa (gage) and exits through sections 2 and 3
(at unknown pressures). The mercury (p = 13,550 kg/m³) U-tube manometer shown is used to
measure the flow rate through section 2 and reads h = 13 cm. The pipe lengths shown in the figure
are a = 0.5 m, b = 2.0 m, and c = 0.5 m. All pipes in the figure have diameter D = 7 cm.
Neglecting frictional losses in the pipes and fittings:
(a) Determine the volume flow rate through section 2.
(b) Calculate the gage pressure at point A.
