BME 101-Quiz 1

Engineering Analysis

Engineering Analysis

the breaking down of an object, system, or problem into its fundamental parts in order to understand their relationships with each other and to outside elements

Frequent aspect in E.A.

mass balance; applying the concept that mass cannot be created nor destroyed

Engineering System

almost anything can be defined as an engineering system and then analyzed

E.S. Examples

buildings, people, animals

E.A. Thermodynamics

the system is the subject of the investigation

Boundary

a closed surface surrounding a system through which energy & mass/matter may enter/leave the system

Surroundings

everything external to the system

Open System

can exchange both matter AND energy with an outside system

Closed System

can exchange energy but NOT matter with an outside system

Isolated System

exchange neither energy NOR matter with an outside system

Mass in an I.S.

is neither created nor destroyed

Mass Balance in C.S.

no mass transport across the boundaries

Verification & Validation

the primary processes for quantifying and building credibility in numerical models

Verification

the process of determining that model implementation accurately represents the conceptual description of the model and its solution

Validation

the process of determining the degree to which a model is an accurate representation of the real world

Limits of V & V

cannot prove that model is correct and accurate for all possible scenarios

Abilities of V & V

can provide evidence that the model is sufficiently accurate for its intended use

Homeostasis

the maintenance of the conditions necessary for life within the body’s internal environment; maintained within certain RANGES

Steady State

parameters defining the state do not change with time; unchanging value/rate over time

Equilibrium

a state of perfect balance

Live biological systems

not at equilibrium
