Fluid Flow Fundamentals (Ohio Timed & Monitored)

In Fluid Flow Fundamentals, you'll learn ...

• How to calculate the mass flow rate and volumetric rate for a fluid system
• The characteristics and flow velocity profiles of laminar and turbulent flow
• The relationship between the Reynolds number and the degree of turbulence of the flow
• How to use simplified and extended Bernoulli equations to solve fluid flow problems

Overview

To meet the Ohio Board's intent that online courses be "paced" by the provider, a timer will be used to record your study time. You will be unable to access the quiz until the required study time of 200 minutes has been met.

This course covers the basics of fluid flow. It begins with a basic principle of fluid flow, the conservation of mass, which leads to the continuity equation-an equation that expresses the relationship between mass flow rates at different points in a fluid system under steady-state flow conditions. The student will learn the difference between laminar and turbulent flow, how to calculate Reynolds Number, and how to do simple piping friction loss calculations.

You will also learn the difference between pressure head, velocity head, and elevation head, which are the components that comprise the Bernoulli Equation-the basic equation of fluid flow. Additionally, this course explains the differences between single-phase and two-phase flow, and it shows how a fluid system containing a centrifugal pump operates.

This course is appropriate for civil and mechanical engineers looking for a refresher course on fluid flow, as well as electrical, control systems, and structural engineers looking to expand their knowledge base.
