Sanoat va muhandislik kommunikatsiya tizimlarida suyuqliklarning quvurlar, kanallar va turli gidravlik elementlar orqali harakati keng tarqalgan jarayon hisoblanadi. Bunday tizimlarda oqim odatda murakkab xarakterga ega bo‘lib, uning asosiy xususiyatlaridan biri — turbulent rejimda kechishidir. Turbulent oqimlar natijasida suyuqlikning mexanik energiyasi o‘zgaradi, bu esa bosim yo‘qolishlari va energiya sarfining ortishiga olib keladi. Gidravlik tizimlarning samaradorligini baholashda bosim yo‘qolishini aniqlash muhim ahamiyatga ega.Iqtiboslar
