Potential Energy Equation
Potential energy
(PE) is defined as the energy of position. Using English system units, it is defined by Equation 111.
In most practical engineering calculations, the acceleration due to gravity (g) is numerically equal to the gravitational constant (g_{c}); thus, the potential energy (PE) in footpoundsforce is numerically equal to the product of the mass (m) in poundsmass times the height (z) in feet above some reference level.
Example:
Determine the potential energy of 50 lbm of water in a storage tank 100 ft above the ground.
Solution:
Using Equation 111
