  1. Question 1 Darcy porous-medium energy equation — dimensions and non-dimensionalization
  2. Question 2 Multi-fluid manometer — gage pressure at A
  3. Question 3 Two reservoirs, two parallel laminar oil pipes
  4. Question 4 Parallel galvanized-iron pipe loop, dead pump as a fixed loss

Paper format. National Exams, December 2019 — 04-Bio-A7, 3 hours, open book (any non-communicating calculator permitted). Four questions constitute a complete exam paper, each of equal value, and all require calculation. All four are solved here.

Check — Question 4 roughness. The paper prints the roughness in Question 4 as “ε=0.15 mm”, and this value is used throughout.

Reference texts. White, Fluid Mechanics, 8th ed. (dimensional analysis and non-dimensionalizing the governing equations, manometry, laminar Hagen–Poiseuille pipe flow, and turbulent Darcy–Weisbach/Colebrook pipe networks — ch. 2, 5, 6).
