Know the basic structure of a hospital and RT department
Know what ATPS is and when it is used
Know what BTPS is and STPD
Know the critical temperature of Oxygen (critical temperature is -183)
What temperature is necessary to liquefy oxygen at 1 atm pressure (-183C)
Temperature conversions
What temperature does all kinetic activity cease
Heat transfer terms (conduction, convection, radiation)
Definition for evaporation, sublimation, saturation and condensation
Viscosity and its relation to flow
Capillary action, convex vs concave what does it mean (When the liquid is water, the meniscus
is concave because the water molecules at the surface adhere to the glass more strongly than
they cohere to each other. In contrast, a mercury meniscus is convex. In this case, the cohesive
forces pulling together the mercury atoms exceed the adhesive forces trying to attract the
mercury to the glass)

o
Grahams Law (Mathematically, the rate of diffusion of a gas is inversely proportional to
the square root of its gram molecular weight. According to this principle, lighter gases
diffuse rapidly, whereas heavy gases diffuse more slowly. Moreover, because diffusion is
based on kinetic activity, anything that increases molecular activity will quicken
diffusion; thus, heating and mechanical agitation speed diffusion)
Ficks law
Henry’s Law (predicts how much of a given gas will dissolve in a liquid. According to this
principle, at a given temperature, the volume of a gas that dissolves in a liquid is equal
to its solubility coefficient times its partial pressure)
Pascals Principle
Poiseuille Principle (the pressure needed to drive a fluid through a tube will increase if
fluid viscosity increases, the tube radius decreases; increasing resistance; The difference
in pressure required to produce a given flow, under conditions of laminar flow through a
smooth tube of fixed size, is defined by Poiseuille’s law: Change in pressure P = 8nl /
r4 ,where P is the driving pressure gradient, n is the viscosity of the fluid, l is the tube

length, is the fluid flow, r is the tube radius, and and 8 are constants)
o Bernoulli/Venturi Principle: (When a fluid flows through a tube of uniform diameter,
pressure decreases progressively over the tube length. When the fluid passes through a
constriction, the pressure drop is much greater. This large pressure drop can be
observed in the fourth water column in Figure 6-24. The eighteenth-century scientist
Daniel Bernoulli was the first to carefully study this effect, which now bears his name.
According to the law of continuity, as the fluid moves into the narrow or constricted
portion of the tube, its velocity must increase (vb > va). According to the Bernoulli
theorem, the higher velocity at point b should result in a lower lateral pressure at that
point (Pb <Pa). Thus, as a fluid flows through the constriction, its velocity increases and
its lateral pressure decreases)
o Continuity
o Daltons Law (Dalton’s law describes the relationship among the partial pressure and the
total pressure in a gas mixture. According to this law, the total pressure of a mixture of
gases must equal the sum of the partial pressures of all component gases. Moreover,
the principle states that the partial pressure of a component gas must be proportional
to its percentage in the mixture)
