Energy Storage Calculations
In Worksheet 4, you will likely encounter calculations involving energy storage systems. Here are some fundamental formulas to keep in mind:
Potential Energy Calculation
The potential energy (PE) of an object can be calculated using the formula:
[ PE = m \cdot g \cdot h ]
Where:
- ( m ) = mass (kg)
- ( g ) = acceleration due to gravity (9.81 m/s²)
- ( h ) = height above a reference point (m)
Kinetic Energy Calculation
The kinetic energy (KE) can be calculated with the formula:
[ KE = \frac{1}{2} m v^2 ]
Where:
- ( m ) = mass (kg)
- ( v ) = velocity (m/s)
Energy Efficiency
Energy efficiency is a critical factor in assessing energy storage systems:
[ \text{Efficiency} (%) = \left( \frac{\text{Useful Energy Output}}{\text{Total Energy Input}} \right) \times 100 ]
Example Problem: Calculating Potential Energy
Problem: A water tank holds 500 kg of water at a height of 10 meters. Calculate the potential energy stored in the tank.
Solution:
Using the formula for potential energy:
[ PE = m \cdot g \cdot h ] [ PE = 500 , \text{kg} \cdot 9.81 , \text{m/s}² \cdot 10 , \text{m} = 49050 , \text{Joules} ]
