Water (ρ = 1000 kg/m³) flows through a horizontal pipe that narrows from 0.10 m to 0.05 m diameter. The velocity in the wide section is 2 m/s. Ignoring losses, find the velocity and pressure drop in the narrow section.
| Step | Working | Result |
|---|---|---|
| Continuity | v₂ = v₁ × (D₁ ÷ D₂)² = 2 × (0.10 ÷ 0.05)² | 8 m/s |
| Bernoulli (horizontal, no losses) | p₁ − p₂ = ½ρ(v₂² − v₁²) = 500 × (64 − 4) | 30,000 Pa |
| Answer | — | Pressure falls by 30 kPa in the narrow section |
This pressure drop is the principle behind the Venturi meter.
Two quick calculations. Water: kinematic viscosity ν = 1.0 × 10⁻⁶ m²/s, ρ = 1000 kg/m³, g = 9.81 m/s².
| Question | Working | Answer |
|---|---|---|
| Water flows at 2 m/s in a 0.1 m diameter pipe. Is the flow laminar or turbulent? | Re = vD ÷ ν = 2 × 0.1 ÷ 1.0 × 10⁻⁶ | Re = 200,000: turbulent (well above about 4,000) |
| Find the gauge pressure 5 m below a water surface | p = ρgh = 1000 × 9.81 × 5 | 49,050 Pa ≈ 49 kPa |
In pipes, flow is usually taken as laminar below about Re = 2,000 and turbulent above about 4,000, with a transition zone in between.
Use the Darcy–Weisbach equation, hf = f (L ÷ D) (v² ÷ 2g), where f is the friction factor. For laminar flow, f = 64 ÷ Re; for turbulent flow, read f from the Moody chart or calculate it with the Colebrook equation using the relative roughness. Add minor losses for fittings with K(v² ÷ 2g).

Most lost marks come from unit errors and unstated assumptions.
| Mark-loser | What to do instead |
|---|---|
| Mixing gauge and absolute pressure | State which you are using |
| Diameter used where radius is needed (or the reverse) | Write the area formula each time |
| Applying Bernoulli across a pump or with large losses | Add pump head and losses to the energy equation |
| Wrong friction factor regime | Calculate Re first |
| Momentum forces with wrong signs | Draw the control volume and axes |
| No units | Keep SI units through every step |
Fluid mechanics is assessed in several formats, and each one is marked on different things. Tutors help you understand the brief and the marking criteria before you start.
| Assessment | What markers look for |
|---|---|
| Problem sets and exams | Clear diagrams, assumptions, correct equations and units |
| Lab reports (for example Venturi, pipe friction or jet impact) | Accurate data, uncertainty analysis and comparison with theory |
| Design assignments | Pipe and pump selection justified with calculations |
| CFD projects | Sound set-up, mesh checks and validated results |
| Dissertations | A clear question, method and well-presented results |
Fluid mechanics students use calculation and simulation tools.
| Tool | What it is used for |
|---|---|
| Moody chart | Friction factors for pipe flow |
| Excel | Iterative pipe and pump calculations |
| MATLAB or Python | Solving equations and plotting results |
| CFD software such as ANSYS Fluent or OpenFOAM | Flow simulation on advanced courses |
| EPANET | Water distribution network analysis |
Fluid mechanics is taught to similar core ideas worldwide, but grading, referencing and course structure differ. FLN tutors work from your own syllabus and handbook and schedule lessons in your time zone. Always follow your module handbook for referencing.
| Country | Where fluid mechanics is studied | Grading | Referencing usually used |
|---|---|---|---|
| United Kingdom | BEng and MEng civil, mechanical and chemical engineering | GCSE 9–1, A-level A*–E; degrees First, 2:1, 2:2, Third | IEEE or Harvard |
| United States | BS engineering fluid mechanics courses | Letter grades A–F and a 4.0 GPA scale | IEEE |
| Australia | BEng fluid mechanics units | HD, D, C, P at university; ATAR for school leavers | IEEE or Harvard |
| Canada | BEng and BASc engineering | Letter grades or percentages; GPA scales vary by province and university | IEEE |
| India | BTech and BE fluid mechanics papers; GATE | Board exam percentages; university CGPA, often on a 10-point scale | IEEE |
Students in Ireland, the Gulf, Europe, Africa and Asia can book the same help, with lessons in their own time zone.
The price of fluid mechanics help depends on the number of problems, whether a lab report is needed and your deadline. A short hydrostatics set costs less than a full pipe network design assignment. You always see the price first: a fixed quote for homework and assignment guidance, or the tutor's hourly rate for live lessons, with no contract and no minimum number of sessions. Refunds follow our refund policy.

Student reviews
Used FLN Tutors? Be one of the first to share how it went, in writing or in a short video.
Yes. Tutors work through problems step by step with diagrams, assumptions and units, so you can solve similar ones yourself.
Bernoulli's equation says that, along a streamline in steady, incompressible, frictionless flow, p + ½ρv² + ρgz is constant.
Use it for steady, incompressible flow along a streamline with negligible friction; add pump head and losses for real pipe systems.
For incompressible flow, the volume flow rate is constant: A₁v₁ = A₂v₂.
Re = ρvD ÷ μ = vD ÷ ν. It compares inertial and viscous forces and predicts whether flow is laminar or turbulent.
Calculate the Reynolds number and the relative roughness ε ÷ D, then read the friction factor where they meet on the chart.
hf = f (L ÷ D)(v² ÷ 2g) gives the head loss due to friction in a pipe of length L and diameter D.
Multiply the pressure at the centroid by the area to find the force, then find the centre of pressure, which is below the centroid.
Apply the momentum equation to a control volume around the bend, including pressure forces and the change in momentum flux in each direction.
It shows that a problem with n variables and k fundamental dimensions can be described by n − k dimensionless groups.
Laminar flow is smooth and orderly at low Reynolds numbers; turbulent flow is chaotic with mixing at high Reynolds numbers.
A pump adds head to the flow; the operating point is where the pump curve meets the system curve.
