LABORATORY PRACTICES Practice PL1. Archimedes' principle [2h].
Objectives: To determine the buoyancy of bodies immersed in liquids. Practical equipment: 1250.1683 Principio de Arquímedes (Didaciencia).

Practice PL2. Measurement of hydrostatic pressure [2h].
Objectives: Measurement of hydrostatic pressure with a U-shaped manometer. Practical equipment: 1250.1676 Manómetro en U con escala (Didaciencia).

Practice PL3. Bernoulli's equation [2h].
Objectives: Study the pressure in pipes with variable and constant diameters through which liquid flows. The vertical tubes indicate the static pressure. Practical equipment: 1250.1689 Principio de Bernoulli (Didaciencia).

Practical PL4 Dimensional analysis and similarity [2h].
Objectives: Apply the learning received in the theoretical sessions on dimensional analysis to a practical problem typical of Fluid Mechanics, specifically to the drag force of a sphere. Practical equipment: GUNT HM 135.

Practical PL5 Flow meters [2h].
Objectives: Measure the flow rate in pipes using differential pressure flowmeters (Venturi, nozzle and calibrated orifice) and rotameter. Measure the velocity inside a pipe with a Pitot-Prandtl tube. Practical equipment: GUNT HM 150.13.

Practice PL6. Demonstration of losses in pipes and connectors [2h].
Objectives: Study of pressure losses in pipes and accessories. Experimental determination of friction factors and loss constants in singular elements. Practical equipment GUNT HM 150.11.

Practice PL7. Supervised work [2h].
Objectives: On the basis of problems posed by the students themselves, following the guidelines established by the lecturer, the students, divided into groups, will have to carry out a project based on a pre-established template based on the Final Degree Project. The aim is to familiarise them with the standard structure of a scientific article, working with formats, references, indexes, etc., as well as the distribution of tasks, teamwork, etc.

The scheduled laboratory or computer classroom practicals may vary in content and order depending on the material available to carry them out, as well as the organisational needs of the academic year.
