What’s on the Continuity & Energy poster
The rule, 3 worked examples, and the mistake everyone makes.
- Mass is conserved along a stream tube, and total head is conserved unless something r…
- Q = A₁v₁ = A₂v₂ · H = z + p/γ + v²/2g
- Area halves = Velocity doubles
- Velocity rises = Pressure head falls
- A real pipe run = Subtract hf downstream
- Common mistake: Applying Bernoulli across a pump → Add the pump head as a term
Educational reference. Continuity and energy are the frame; a real system needs loss terms and a design standard.

- Who is the Continuity & Energy poster for?
- Continuity & Energy belongs to the Civil Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning water resources can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Continuity & Energy poster?
- Any time flow changes section, level or pressure. A wall chart earns its place by being glanceable from where the work is happening, so Continuity & Energy belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
- What other posters go with Continuity & Energy?
- Culvert Design, Groundwater & Wells and The Water Balance sit alongside Continuity & Energy in the Civil Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.Culvert DesignGroundwater & WellsThe Water Balance
- Is the Continuity & Energy poster free to download and print?
- Yes. Continuity & Energy downloads as a free PDF with no account, no email and no watermark, like everything else in the Civil Engineering section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Continuity & Energy poster print at?
- Continuity & Energy is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Continuity & Energy loses nothing.Printing guide
