Stefan–Boltzmann law
P = σAeT⁴
Where: A = area (m²) / amplitude, P = power (W) / pressure (Pa), T = time period (s) / temperature (K) / tension (N), e = electron charge (C) / coefficient of restitution, σ = Stefan–Boltzmann constant / surface charge density
Solved example
Given: A = 7, T = 5, e = 10, sigma = 4
Find: P (power (W) / pressure (Pa))
- Formula: P = A·T⁴·e·σ
- Substitute the values: P = 10·4·5⁴·7
- Result: P = 175000 W
Answer: P = 175000 W
