Questions and Answers

What is the formula to calculate the temperature distribution in a material over time?

  • $T(x, t) = T_0 + \sum_{n=1}^\infty \left(\frac{4T_0}{\pi n}\right) \sin\left(\frac{n\pi x}{L}\right) e^{-\alpha (n\pi/L)^2 t}$ (correct)
  • $T(x, t) = T_0 + \sum_{n=0}^\infty \left(\frac{4T_0}{\pi (2n+1)}\right) \cos\left(\frac{(2n+1)\pi x}{2L}\right) e^{-\alpha ((2n+1)\pi/2L)^2 t}$
  • $T(x, t) = T_0 + \sum_{n=1}^\infty \left(\frac{4T_0}{\pi n} \right) \cos\left(\frac{n\pi x}{L}\right) e^{-\alpha (n\pi/L)^2 t}$
  • $T(x, t) = T_0 + \sum_{n=0}^\infty \left(\frac{4T_0}{\pi (2n+1)}\right) \sin\left(\frac{(2n+1)\pi x}{2L}\right) e^{-\alpha ((2n+1)\pi/2L)^2 t}$
