Given:

  • k_1 = 50
  • k_2 = 0.04
  • k_3 = 1.4
  • t_1 = 0.02
  • t_2 = 0.1
  • t_3 = 0.015
  • delta_t = 40

Expected Result:

  • q_flux = 15.929183401791

Engineering Interpretation:

Under the given input conditions, the calculated result is: q_flux = 15.929183401791 W/m^2.

The actual numerical result is computed by the Runtime engine using the persisted tool definition. The values shown here come from deterministically validated test cases.

Formula / Method

q_flux = delta_t / (t_1/k_1 + t_2/k_2 + t_3/k_3)
