Answer
Ma'auni na ka'idar $P$ na maɓuɓɓugar ruwan raƙuman ruwa na Crest-to-Crest an samo shi ne daga tsarin karkatar da katako wanda aka daidaita don lissafin sinusoidal. Ma'auni na daidaitattun shine $ P = \ frac {E b t ^ 3 N f K}{D_m^3 n}$ inda $E$ shine Modulus of Elasticity, $ b$ shine bangon radial, $ t $ shine kauri na kayan, $ N $ shine adadin raƙuman ruwa a kowane juyi, $ f$ shine juyawa, $ D_m $ shine ma'anar diamita, da $ n $ s. Modulus na Elasticity $ E$ yana da mahimmanci yayin da yake bayyana taurin; alal misali, yin amfani da 17-7PH CH900 ($ E \ kimanin 200$ GPa) tare da Inconel X-750 ($ E \ kimanin 213$ GPa) yana canza yanayin bazara $ k = P/f$. Ana kiyaye kewayon linzamin kwamfuta yawanci tsakanin $20%$ da $80%$ na jujjuyawar da ake da su kafin a gama ƙasa ko shigar da yankin da ba na madaidaici ba inda $f> 0.8(h-t)$.
