EKSPLUATATSIYA HOLATIDAGI MAGISTRAL KANALLAR O'ZANIDA GIDRAVLIK ENERGIYA YO'QOTISHLARI
Abstract
Ushbu maqolada magistral irrigatsiya kanallarida ekspluatatsiya jarayonida yuzaga keladigan gidravlik qarshiliklar tahlil qilingan. Kanallar tubida cho’kindi hosil bo’lishi, o’simliklar o’sishi, devorlarning deformatsiyalanishi va boshqa omillarning gidravlik qarshiliklarga ta’siri o’rganilgan. Darcy–Weisbach tenglamasi va Manning formulasi asosida turli ekspluatatsiya holatlarida gidravlik qarshilik koeffitsientlarini aniqlash metodologiyasi taklif etilgan. Amaliy o’lchov ma’lumotlari asosida kanal kesimida g'adir-budirlik koeffitsientining o’zgarish qonuniyatlari aniqlangan. Natijalar kanal ekspluatatsiyasini optimallashtirish va ta’mirlash rejalarini ishlab chiqishda foydalanish uchun tavsiya etiladi.
