Transcript Energy Systems, Prime Movers and Force



There are 4 energy systems:
Thermal, Electrical, Mechanical and Fluid
A prime mover is present in each system
System
Prime Mover
Symbol
Mechanical
Force (a change in)
∆F
Thermal
Temperature
Difference(change in)
∆T
Electrical
Voltage (change in)
∆V
Fluid
Pressure (change in)
∆P
A difference or change in(∆) gradient (usually high to low)
in an energy system causes movement (hence “mover”)
Depending on the system and prime mover, there will
either be movement of mass(mechanical), temperature
difference(thermal), electrons(voltage) or fluids (pressure)

In many cases, energy systems work in
combination with one another
A chemical and mechanical planar used as part
of the computer chip making process in a
semiconductor factory relies on all 4 systems:
CMP machine
1. What is a prime mover?
2. How many are there in total?
3. List each prime mover and the system to which it
belongs.
4. What is force?
5. How does force relate to the prime movers?
6.
Identify 1 practical item from your reading that is
an example of each system and its prime movers.
7.
A “change in” or “difference in” a prime mover is
required for an energy system to be present. What
greek letter(symbol and word) is used to
represent a “change in” or “difference in”?
