64.2 Basic Turbine Engine Theory

64.2.2 Describe Newton's third law of motion and its practical application as it relates to the operation of a turbine engine. 

Newton's third law: 

If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.

"For every action there is an equal and opposite reaction."

 

 

64.2.4 Describe how gas undergoes changes in pressure, volume and temperature in accordance with Boyle's and Charles' Laws. 

Boyle's Law

Formulated by the physicist Robert Boyle in 1662, states that the pressure (p) of a given quantity of gas varies inversely with its volume (v) at constant temperature.

Example:  

In the lungs - 

Inhale - Volume increases = Pressure reduces

Exhale - Volume decreases = Pressure increases

 

Charles' Law

First suggested by the French physicist J.A.C. Charles about 1787, states that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant
