Marine Foundations

Ships, seawater and fluid basics. Ship types, dimensions and tonnage, plus the fluid properties, hydrostatic pressure and flow regimes every ship calculation builds on.

• Introduction to Marine Engineering & Ship Types — Ships, the machines that carry 80–90% of world trade. Learn what marine engineers and naval architects do, ship types (bulk carriers, tankers, container ships, LNG carriers, ro-ro, offshore vessels, naval ships), main dimensions and form coefficients, displacement, deadweight and tonnage, the engine room and its systems, careers at sea and ashore — with Python for displacement, deadweight and Froude number.
• Fluid Properties — Fluids deform continuously under shear. Learn density, specific weight and gravity, viscosity (dynamic and kinematic), Newtonian vs non-Newtonian fluids, compressibility, surface tension, capillarity and vapour pressure.
• Pressure — Pressure is force per unit area in a fluid. Learn hydrostatic pressure p = ρgh, absolute vs gauge pressure, manometers, Pascal's law and hydraulic presses, forces on submerged surfaces and buoyancy.
• Laminar/Turbulent Flow — Flow is smooth (laminar) or chaotic (turbulent) depending on the Reynolds number. Learn Re, transition, velocity profiles, boundary layers and why turbulence matters for mixing, heat transfer and pressure loss.
