Viscous fluid flow Study guides, Class notes & Summaries

Mechanical ASVAB Latest Update (Scored A) force Changes the velocity of an object friction Acts in opposition to motion, causes effort work to be larger than load work equilibrium Net force is zero when velocity is not changing viscous drag Like friction, however increases with speed, varies by shape gravity Causes objects to fall mass Amount of substance weight Force of gravity on a mass lift Caused by higher speed air flow over a lower speed air flow camber When a surface is curved ai...

laminar flow - Answer-- A streamline or viscous flow. - layers of water flowing over one another at different speeds with virtually no mixing between layers. - Fluid particles move in definite and observable paths or stream lines. - The flow is characteristic of viscous (thick) fluid or is one in which viscosity of the fluid plays a significant part. turbulent flow - Answer-Irregular movement of particles of the fluid. What do you use to determine quantity of air flowing through the duc...

"CFD" stands for ... correct answer: Computational Fluid Dynamics CFD and Computational Aerodynamics are different names for the same thing (True or False) correct answer: False The four primary steps in the CFD process are correct answer: geometry modeling, grid generation, flow solution, post processing CFD methods are also known as "low-fidelity methods" (True or False) correct answer: False FD techniques may only be used to model air as the working fluid (True or False) c...

Fluid Mechanics Exam 2 Concepts || With Complete Solutions (100% Correct) Fluid Mechanics Exam 2 Concepts || With Complete Solutions (100% Correct) What is a streamline? - ANSWER - An imaginary line through flowing fluid such that velocity is tangent to it at every point. What are different components of acceleration? - ANSWER - Local: dv/dt Convective: v*dv/dx Centripital: v^2/r What is the basic assumption involved in the Euler Equation? - ANSWER - Mass is constant What assumpti...

Fluid regulation mechanisms - Answer--The thirst center. The thirst center in the hypothalamus stimulates or inhibits the desire for a person to drink. -Antidiuretic hormone. ADH regulates the amount of water the kidney tubules absorb and is released in response to low blood volume or in response to an increase in the concentration of sodium and other solutes in the intravascular fluids. -The RAAS. The RAA system controls fluid volume, in which when the blood volume decreases, blood flow t...

Basics of diffusion, gradients, and how they relate - Answer-Diffusion: spontaneous movement of very small things. It requires no energy investment by the organism (other than keeping the temperature above freezing) --direction is random Gradients: top of gradient = high concentration, bottom of gradient = low concentration --diffuses high to low Basics of diffusion across a semipermeable barrier - AnswerFactors that speed up or slow down diffusion - Answer-size: smaller things diffuse fas...

Bio_235_Final_review CHAPTER 19 1. Describe the functions of blood. A. Blood: is a liquid connective tissue that consists of cells surrounded by a liquid extracellular matrix. The extracellular matrix is called blood plasma, and it suspends various cells and cell fragments. B. interstitial fluid: is the fluid that bathes body cells and is constantly renewed by the blood. C. functions of blood: Blood transports oxygen from the lungs and nutrients from the gastrointestinal tract, which d...
