- [The drag reduction of carboxymethil cellulose in liquid has been studied as concentration function by using square pipe 6x6 mm. Experiments are done by measuring the pressure drop. The purpose of this study is to observe the pressure drop in the square pipe 6x6 mm with the addition of carboxymethil cellulose concentration in liquid. 6x6 mm-in-dimension of square pipe is used in this study with a variation of carboxymethil cellulose solution with a concentration of 200 ppm, 400 ppm and 600 ppm. Experiments has been done according to 28000 of Reynolds number. Ratio of drag reduction which is 51,63% on the Reynolds figure 25500. The decrease of coefficient of friction indicates the effectivity of the test fluid xanthan gum, that can be seen from the coefficient of friction graphics towards Blasius line graphics. , Pengurangan hambatan karboksimetil selulosa dalam larutan air telah dipelajari sebagai fungsi konsentrasi dengan menggunakan pipa kotak 6x6 mm. Percobaan dilakukan dengan mengukur tekanan jatuh (pressure drop). Tujuan penelitian ini untuk meneliti pressure drop dalam pipa kotak 6x6 mm dengan penambahan konsentrasi karboksimetil selulosa dalam larutan air. Pipa kotak berdimensi 6x6 mm digunakan dalam penelitian ini dengan variasi larutan karboksimetil selulosa konsentrasi 200 ppm, 400 ppm dan 600 ppm. Percobaan dilakukan hingga bilangan Reynolds 28000. Rasio penurunan hambatan (drag reduction) maksimum yaitu 51,63% pada bilangan Reynolds 25500. Penurunan koefisien gesek mengindikasikan keefektifan fluida uji karboksimetil selulosa yang dapat dilihat dari grafik koefisien gesek terhadap garis grafik Blasius. ]
