Fluid Mechanics notes KNEC Diploma

INTRODUCTION

Fluid Mechanics falls under a broader area of study known as Applied Mechanics and it deals with statics and dynamics of liquids and gases

The study of Fluid Mechanics is divided into Fluid Statics and Fluid Dynamics.

Fluid Statics deals with fluids at rest under pressure while Fluid Dynamics deals with fluids in motion. Fluid Mechanics mainly deals with liquids whose properties include surface tension, density and viscosity.

The purpose of the module unit is to equip the trainee with the necessary knowledge that will help them when dealing with various materials and equipment on a production line, workshops and other work places.

Trainees taking this module unit require prior training in relevant mathematics and mechanical science that are found in module I and module II of this course.
