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))

  1. Formula: P = A·T⁴·e·σ
  2. Substitute the values: P = 10·4·5⁴·7
  3. Result: P = 175000 W

Answer: P = 175000 W
