[ABSTRAK
Perhitungan effisiensi suatu aliran fluida akan menjadi suatu hal penting di dalam kehidupansehari - hari, dalam suatu aplikasi industri atau area lain yang memanfaatkan suatu aliran darifluida. Banyak insinyur yang telah mengkonsentrasikan ilmunya untuk lebih jauh mengetahuitentang sifat ? sifat dari suatu aliran,fluida dengan tujuan akhir adalah bagaimana kita dapatmengendalikan suatu aliran dengan efektif dan effisien di dalam aplikasi nyata. Variabel ?variabel yang diperhitungkan dalam pemanfaatan aliran seperti kecepatan aliran, debit aliran,temperatur fluida, viskositas fluida, penampang aliran dan lain ? lain yang saling bersinergi satusama lain telah jauh dikembangkan agar tujuan tersebut bisa tercapai. Salah satu teknik yangdipakai untuk memberikan debit fluida yang lebih besar dengan tenaga yang sama adalah denganpenambahan zat aditif (agen) pada fluida yang secara langsung akan merubah sifat viskositasfluida tersebut dan mempengaruhi aliran yang terjadi, disinilah pentingnya kita mengetahui sifat? sifat yang terjadi pada suatu aliran fluida jika ditambahkan agen tertentu. Tujuan daripenelitian dan percobaan ini adalah untuk mengetahui sejauh apa pengaruh dari penambahanagen yaitu tinta pada fluida air dalam suatu aliran turbulen di dalam pipa lurus yang di plot padaperbandingan suatu grafik kecepatan aliran yang terjadi. Diameter yang akan digunakan yaituؽ? dengan panjang pipa total 5 meter. Variasi dari konsentrasi campurannya menggunakan 2variasi konsentrasi yaitu sebesar 3 ppm dan 7 ppm. Hubungan koefisien gesek dengan generalisbilangan Reynolds mennjukkan semakin tinggi kepadatan lumpur diikuti kenaikan nilai koefisiengesek.;
ABSTRACT
Efficiency calculation in some flow of fluids, will become something very important matter indaily lives, in some industrial application or another area which using fluids current flow.. Manyengineer that has been concentrating their knowledge to understand more about characteristic ofa current flow of fluids so that they can produce and control a current flow of fluids in a veryeffective and efficient way in some real practice. The variables that calculated in a current flowof fluids such as fluids viscosity, volume, temperature, dimension and others has been developedto some extend so they can achieve a very efficient application. One technique that can be usedto give a better efficient current of fluids flow is to add some agent on fluids, which can directlychange the character of fluids that can be used in a better way. This is the matter that howimportant why we must understand the characteristic of a fluids and what happen to it if we addsome agent to it. The goal of this research and testing is to know how far effect of some agentwhich in this case is ink solution effect in a wsome turbulent water current flow on a straightpipe. The research will be comparing a two graphic of pure water and ink solution effect currentflow. The diameter of pipe is ؽ? with total length of 5 [m]. The variation of concentrationagent is at 3[ppm], and 7[ppm]., Efficiency calculation in some flow of fluids, will become something very important matter indaily lives, in some industrial application or another area which using fluids current flow..
