ENGR 01341 — Fluid Mechanics

Lab videos and handouts below reflect the versions originally posted; if you are in my section, always check Canvas for the latest updates.

Laboratory Resources

Excel for data analysis

Lab 1 — Excel for Data Analysis

Spreadsheet formulas (absolute/relative), and publication-quality charts.

Synopsis: Intro to spreadsheet skills for data analysis and figures. Google Docs is great for collaboration, but Excel is preferred for high-quality plots.

Tensiometer for surface tension measurement

Lab 2 — Measurement of Fluid Properties

Density, viscosity, surface tension; instrument handling and calibration.

Synopsis: Introduces key fluid properties and use of lab instruments.

Hydrostatic force apparatus

Lab 3 — Hydrostatic Force

Center of pressure for submerged/partially submerged bodies.

Synopsis: Use the hydrostatic force apparatus to compute center of pressure on a rectangular face.

Impact of jet apparatus

Lab 4 — Impact of Jet

Force due to a jet on plates at different angles; force–flowrate relation.

Synopsis: Collect data at several flowrates and compute forces on angled targets.

Free jet trajectory test

Lab 5 — Orifice & Free Jet

Jet trajectory; Torricelli; overall coefficient of discharge.

Synopsis: Compare loss due to contraction (vena contracta) and drag; estimate discharge coefficient.

Venturi apparatus with piezometers

Lab 6 — Bernoulli’s Principle

Venturi pressure drop; piezometer readings; total head balance.

Synopsis: Compare pressure/velocity heads; estimate losses and check total head constancy.

Flowmeter calibration setup

Lab 7 — Flowmeter Calibration

Compare venturi, orifice plate & rotameter; compute loss coefficients.

Synopsis: Compare experiment vs. theory and discuss uncertainty.

Pipe network with fittings

Lab 8 — Energy Losses in Pipes

Minor losses across fittings; pressure drops; K-loss estimation.

Synopsis: Build a loss table; compare predicted vs. measured Δp across fittings.
