What’s on the Bernoulli's Equation poster?
The rule, 3 worked examples, and the mistake everyone makes. Along a streamline in ideal flow, pressure head, velocity head and elevation add to a…; p ÷ ρg + V² ÷ 2g + z = constant; Venturi throat = Faster, so lower pressure; Pitot tube = Δp = ½ρV²; Tank orifice, head h = V = √(2gh); Common mistake: Applying it across a pump or a valve → Only where nothing is added or…. Add pump head and friction head and Bernoulli becomes the steady-flow energy equation for a pipeline.
Who is the Bernoulli's Equation poster for?
Bernoulli's Equation belongs to the Mechanical Engineering section rather than to a school year, because engineering is not something one grade owns. Anyone learning thermofluids can pin it up — a beginner, a student mid-course, or someone revising years later.
When should you use the Bernoulli's Equation poster?
Venturis, pitot tubes, orifices, and any short run where losses are small. A wall chart earns its place by being glanceable from where the work is happening, so Bernoulli's Equation belongs on the wall where that engineering work actually happens, within glancing distance, rather than filed away.
What other posters go with Bernoulli's Equation?
Continuity, Drag & Lift and Entropy & Irreversibility sit alongside Bernoulli's Equation in the Mechanical Engineering section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.ContinuityDrag & LiftEntropy & Irreversibility
Is the Bernoulli's Equation poster free to download and print?
Yes. Bernoulli's Equation downloads as a free PDF with no account, no email and no watermark, like everything else in the Mechanical 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 Bernoulli's Equation poster print at?
Bernoulli's Equation 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 Bernoulli's Equation loses nothing.Printing guide
