Answer
A cikin bazara mai juyi juye-juye, adadin raƙuman ruwa $N$ yana da tasiri sosai akan yanayin bazara $k$ da rarraba damuwa. Bisa ga dabarar $k ∝ N^4$, ƙananan canje-canje a cikin $N $ suna haifar da canje-canje masu mahimmanci a cikin taurin. Don ƙayyadaddun aikace-aikace, ƙididdige yawan igiyoyin igiyar ruwa (misali, $ N=5$ ko $7$) yana samar da daidaiton daidaito da ƙima saboda yana ƙara adadin wuraren tuntuɓar, ta haka yana rage tazara tsakanin raƙuman ruwa da rage lokacin lanƙwasawa $M = \ frac{P D_m}{4 N}$. Koyaya, yayin da $ N$ ke ƙaruwa, jujjuyawar da aka yarda kafin raƙuman ruwa su fara tsoma baki tare da juna (camuwa) yana raguwa. Dole ne masu zanen kaya su daidaita $ N$ don cimma nauyin da ake buƙata yayin da suke riƙe amintaccen damuwa na aiki a ƙasa da iyakacin roba $\sigma_e = \ frac{3 π P D_m}{4 b t^2 N^2}$.
