Laminar Vs. Turbulent Flow

Apr 02, 2018Laminar vs. turbulent flow can characterize how fluid is moving, with a laminar flow being a more smooth, orderly flow, and a turbulent flow being rough and chaotic. Laminar flow has a constant velocity at any point within the fluid, imagine similar to a constant flow of traffic. Turbulent flow is chaotic, forms eddies and whirlpools and is similar to the flow of a whitewater rapid.

Understanding the Flow of Electrical Current

Jun 29, 2021For most people, electricity is a mysterious force that somehow magically appears when we flip a light switch or plug in an appliance.

Thermodynamics of Living Systems

Peter Molton has defined life as regions of order which use energy to maintain their organization against the disruptive force of entropy. 1 In Chapter 7 it has been shown that energy and/or mass flow through a system can constrain it far from equilibrium, resulting in an increase in order. Thus, it is thermodynamically possible to develop complex living forms, assuming the energy flow
