上記、水の粘度のデータに一部誤りがありました。2016年12月5日 訂正いたしました。情報ありがとうございました。
粘度 1 mPa・s = 1 cP (センチポアズ)
粘度 1 Pa・s = 1000 mPa・s = 1000 cP
動粘度 1 cSt = 1 mm^2/s
動粘度 = (静)粘度 ÷ 密度
(静)粘度 = 動粘度 × 密度
例1.動粘度 1.25 cSt 密度 0.8g/cm^3 の液体の(静)粘度 cP はいくらか?
(静)粘度 = 動粘度 × 密度
= 1.25 × 0.8
= 1.0 cP = 1.0 mPa・s
例2.動粘度 1.25 cSt 密度 1.2g/cm^3 の液体の(静)粘度 cP はいくらか?
(静)粘度 = 動粘度 × 密度
= 1.25 × 1.2
= 1.5 cP = 1.5 mPa・s
例3.(静)粘度 1.25 cP 密度 0.8g/cm^3 の液体の動粘度 cSt はいくらか?
動粘度 = (静)粘度 ÷ 密度
= 1.25 ÷ 0.8
= 1.5625 cSt
例4.(静)粘度 1.25 cP 密度 1.2g/cm^3 の液体の動粘度 cSt はいくらか?
動粘度 = (静)粘度 ÷ 密度
= 1.25 ÷ 1.2
= 1.0417 cSt
