Cards

Term
ampere
Definition
measurement of electric current
Term
volt
Definition
measurement for voltage
Term
Ohm's Law ^ ^
Definition

V = I × R

Voltage - Current - Resistance

if the resistance is constant, increases in voltage cause increases in current flow.

Term
reducing the likelihood of electrical accidents
Definition

grounding

GFCI's

no trans-cutaneous conductors

Term
Helium (He)
Definition
−267.9         2.3
Term
Oxygen (O2)
Definition
−118.8           49.7
Term
Carbon dioxide (CO2)
Definition
31.1          73
Term
Nitrous oxide (N2O)
Definition
36.5            71.8
Term
Boyle's law
Definition

Boil - Temperature is constant

pressure up > volume down

P1V1 = P2V2

TEMPERATURE HAS TO BE IN KELVIN!!!!

Term
Charles' Law
Definition

Constant is Pressure

T up = V up

V1 / T1 = V2 / T2

TEMPERATURE HAS TO BE IN KELVIN!!!!

Term
Gay-Lussac's Law
Definition

Constant is Volume

Pressure up - Temperature up

P1 / T1 = P2 / T2

TEMPERATURE HAS TO BE IN KELVIN!!!!

Term
Density
Definition

Density is the ratio of a substance's mass to its volume.

D = M / V

Term
Reynolds' Number
Definition

Over 2000 = Turbulent flow

Under 2000 = Laminar flow

Term
Bernoulli Principle
Definition

PF1 = PF2

 

Pressure (wall) - Flow

 

speed up = less pressure

Term
Fick's Law of Diffusion
Definition

Vgas = A × D × (P1 - P2)


/ T

 

Area x Diffusion x Pressure difference

 

divided by

 

Thickness

Term
The Coanda effect
Definition

P1 x F1 = P2 x F2

Pressure - Flow

 

The basis for fluidic devices used in several mechanical ventilators
