Atmospheric pressure - ANSWERS-· Atmospheric pressure is a force in an area
pushed against a surface by the weight of the atmosphere of Earth, a layer of
air. ... This is because high places do not have as much air above them,
pushing down. Barometers can be used to measure atmospheric pressure.
There is the same atmospheric pressure from all directions.
Absolute Pressure - ANSWERS-· Absolute pressure is a pressure that is relative
to the zero pressure in the empty, air-free space of the universe. This
reference pressure is the ideal or absolute vacuum. It is denoted with the
subscript "abs": Pabs.
Laminar flow - ANSWERS-· Laminar flow is a flow regime characterized by
high momentum diffusion and low momentum convection. When a fluid is
flowing through a closed channel such as a pipe or between two flat plates,
either of two types of flow may occur depending on the velocity and viscosity
of the fluid: laminar flow or turbulent flow.
, Static pressure - ANSWERS-· Static pressure is one of the most important
factors in HVAC design. Simply put, static pressure refers to the resistance to
airflow in a heating and cooling system's components and duct work. The
push of the air must be greater than the resistance to the flow or no air will
circulate through the ducts
Boyles Law - ANSWERS-· Boyle's law is a gas law, stating that the pressure and
volume of a gas have an inverse relationship. If volume increases, then
pressure decreases and vice versa, when temperature is held constant.
Volumetric flow rate - ANSWERS-· the volumetric flow rate (also known as
volume flow rate, rate of fluid flow or volume velocity) is the volume of fluid
which passes per unit time; usually represented by the symbol Q (sometimes
V̇ ). The SI unit is cubic metres per second (m3/s).
Instantenous velocity - ANSWERS-· Instantaneous velocity is the velocity of an
object in motion at a specific point in time. This is determined similarly to
average velocity, but we narrow the period of time so that it approaches zero.
If an object has a standard velocity over a period of time, its average and
instantaneous velocities may be the same.
A force - ANSWERS-a force is any interaction that, when unopposed, will
change the motion of an object. A force can cause an object with mass to
change its velocity (which includes to begin moving from a state of rest), i.e.,
to accelerate. Force can also be described intuitively as a push or a pull
Net force - ANSWERS-· Net force is the vector sum of forces acting on a
particle or body. The net force is a single force that replaces the effect of the
original forces on the particle's motion. It gives the particle the same
