### Course content

The course deals with both liquids that are at rest and that are in motion. It includes the physical properties of liquids, hydrostatics and dynamic equations of motion as well as the principles of conservation of mass and conservation of energy and the impulse rate. Special emphasis is placed on basic areas of application such as pipe flow, channel flow, linear wave theory as well as drag and lifting forces on bodies and structures.

Basic fluid mechanics: hydrostatics, water continuity, momentum equation, Bernoulli's equation, Energy equation, Navier-Stokes equation, pipe and channel flow, singular and friction losses, Manning+Chezy's equations, Darcy-Weissbachs equation, Moody's diagram, drag and lift, linear wave theory etc.

### Learning outcome

Knowledge

The student shall have the knowledge about

• how basic equations for fluid flow can be derived
• which equations can be used to solve practical problems in different flow situations
• typical hydraulic situations for constructions of hydropower plants, river protection structures, water supply plants, ports and fixed marine structures.
• how laboratory and numerical models can describe complex flow fields.

Skills

The student should be able to

• Calculate energy loss in piping systems, power of hydropower plants and required capacity of pumps.
• Calculate water level jumps and capacity of overflows.
• Calculate hydrostatic forces on dived bodies and hatches.
• Calculate the motion of non-refracting surface waves on water, according to linear wave theory, and the load such waves give on circular-cylindrical structures.
• Calculate the hydrostatic stability of floating barges and the like for different loads.

General competance

• The student will manage to see the connection between basic equations and solution of practical flow problems
• know which problems can be computed with simplified approaches and which cases that need more knowledge

### Learning methods and activities

Lectures, compulsory homework and labwork. Voluntary web based excercises. In total there are 12 exercises in the course, whereas 8 of 12 must be approved within the deadline to be accepted for the exam. Mandatory lab exercise. Help from student assistants available for calculations.

• Exercises

### Further on evaluation

The exam is 4 hours digital school exam.

### Required previous knowledge

The course is taught in Norwegian language only, so the students have to know this language.

### Course materials

Class notes in Norwegian, written by Geir Moe. Class notes in Norwegian, written by Nils Reidar Olsen. The book "Engineering Fluid Mechanics", 9/10. ed, 2010/2014 by Elger, Williams, Crowe, Roberson.
