English

#### Summary

This course helps students acquire basic knowledge of the main concepts and equations of fluid mechanics and develop the skills necessary to work effectively in professional engineering practice.

#### Content

• Introduction: Continuum assumption, basic fluid properties
• Fluid statics: pressure, forces on immersed body
• Flowing fluids and pressure variation: continuity, momentum, energy equations, applications in engineering
• Dimensional analysis and similitude
• Surface resistance
• Flow in conduits
• Flow in open channels
• Flow measurement

#### Learning Prerequisites

##### Recommended courses

Physics, Mathematics, Mechanics

#### Learning Outcomes

By the end of the course, the student must be able to:
• Describe basic fluid and flow characteristics such as density, viscosity, surface tension, shear stress, pressure and velocity.
• Apply the hydrostatic equation and the buoyancy equation to predict forces and moments.
• Apply the Bernouilli equation to calculate pressure and velocity variations in a fluid flow.
• Apply the contintuity equation to draining tanks and reservoirs.
• Apply the momentum equation to stationary and moving control volumes.
• Apply the energy equation to predict variables such as pressure drop and head loss.
• Apply the Buckingham-Pi theorem to determine dimensionless variables.
• Design pipes and pumps based on pressure drop and head loss calculations.
• Apply Manning's equation to uniform open channel flow and find the best hydraulic section.
