How the model reads against this maker's data

Fan power through the fan laws, one curve per fan from a US multi-rating table

2 276 cells over 12 fans; 8 withheld by name

every held cell's BHP within 2 % plus the half-hundredth it is printed to (the worst at 0.76 of that band; none from 0.5 BHP past a bare 2 %) and its speed within 0.35 %, read back by the solver's own fan-law solve; RMS 0.24 % on power over the 2 206 cells from 0.5 BHP up. Withheld: eight cells, each the last of its row and past the fan's pressure peak

From the validation page; every row is held by a test.

Listed from published data; a listing's figures are the manufacturer's, the model that runs them is ours. Solver results never depend on who has claimed what.
