General description and relevant information <div><p><u>General description of the subject</u></p><p>A set of experimental laboratory practicals will be carried out in order to obtain a practical knowledge of fluid conduction systems and the elements that characterize them: pumps in operation, pressure losses, operation of devices and accessories, flow measurement, etc. Some of these sessions are virtual and use software or applications designed for telematic use. From the pool of practicals specified in the contents, a selection of 8 will be made to evaluate the subject. They will appear in moodle when the course begins.</p></div>

Topic Sub-topic
Pràctica 2 Assess the viscosity of liquids with a rotary viscometer.
Pràctica 1 Assess the viscosity of liquids with the Cannon-Fenske viscometer. Analyze the dependence of viscosity with concentration and temperature.
Pràctica 3 Observe the qualitative differences between the different flow regimes (laminar, transitional and turbulent) in a pipe of circular section.
Pràctica 4 Measure the force exerted by an impinging jet over different types of static plates.
Pràctica 5 Measure the resultant force due to hydrostatic pressure acting on a flat surface partially or fully submerged in a liquid in equilibrium.
Pràctica 6 Determine the velocity profile and pressure drop of air circulating inside a pipe.
Pràctica 7 Calibrate different flow meters: orifice plate, venturimeter and variable section rotameter.
Pràctica 8 Determine the operating characteristics of a Pelton turbine at different speeds and study the variation of engine torque, power, discharge and performance of the turbine according to its rotational speed.
Pràctica 9 Determine the characteristic H-Q curves of two simple centrifugal pumps at a fixed rotation speed and of two centrifugal pumps associated in series and in parallel.
Pràctica 10 Determine the characteristics of water hammer in a pipe produced by the sudden closing of a valve.
Pràctica 11 Determine the characteristics of the oscillation of a cylindrical column of fluid caused by pressure variations in a pipe after the sudden closing of a valve
Pràctica 12 Determine the distribution of the average velocity at the exit of a circular jet from measurements of pressure differences and analyze how it is related to the flow rate, the flow of momentum and kinetic energy at different distances from the jet exit
Pràctica 13
Use EPANET to model a water supply network, obtain velocities and pressures in pipelines, and simulate different typical problems in these systems
Pràctica 14 1) Use FluidSim to model and simulate some elementary pneumatic circuits, to 2) build them with the elements of the laboratory pneumatic bench, observing and describing their operation

  Description
Laboratory practicals Laboratory experiments on the equipment for fluid traffic in engineering practice, and analysis of related phenomena
Introductory activities Presentation of the practicals
IT-based practicals Apply statistical and error propagation analysis to the results of laboratory practicals to elaborate the data according to scientific criteria.
Personal attention In the hours devoted to consultations

Personalized attention
Description

The student has online or face-to-face consultation hours with the internship teachers, outside of internship hours. Appointments can be scheduled via moodle. Any questions can also be posed during the laboratory sessions. As well, doubts may be channeled through the moodle forum. Email inquiries will not be accepted. For teachers' availability times, consult the subject's moodle.

Other comments and second exam session

The final mark will be the weighted average of all grades. There is no minimum grade in any part. There is no second call. Failure will imply doing the practicals again the following year (the report grades are not saved).

The final exam is not mandatory, if the grade before the exam has reached 5.
