“…У Львівській політехніці винайдено спосіб регулювання шляхового роздавання рідини з напірних РТ з насадками [Cherniuk et al, 2017]. Ми досліджуємо вплив геометричних характеристик РТ і вихідних насадок на пропускну здатність останніх [Bosak et al, 2019;Cherniuk et al, 2020;Bihun et al, 2019], а також роботу напірних трубопроводівзбирачів [Cherniuk et al, 2017].…”

Розглянуто основні галузі застосування напірних розподільних трубопроводів дискретним шляховим роздаванням рідини. Це такі галузі: іригація (краплинне, внутрішньоґрунтове й поверхневе зрошення); водопостачання та водовідведення (трубчасті розподільні системи очисних споруд, протипожежні системи); енергетика (охолодження циркуляційної води в атомних і теплових електростанціях (бризкальні басейни та градирні); вентиляція (припливні системи); сільськогосподарська авіація (обприскування рослин); хімічне виробництво; машинобудування (паливні розподільні магістралі багатоциліндрових двигунів внутрішнього згоряння) тощо. Наведено схеми їх влаштування й описано принципи роботи. У довгих розподільних трубопроводах напір уздовж потоку спадає, що спричиняє нерівномірність шляхового роздавання рідини. Однак, у переважній більшості виробничих процесів ставиться завдання забезпечення рівномірного роздавання рідини по усій довжині розподільного трубопроводу. Пошук способів зменшення шляхової нерівномірності роботи розподільних трубопроводів триває. Це актуальна наукова проблема, котру потрібно вирішити, розвиваючи методи розрахунку. Ключові слова: напірні розподільні трубопроводи; шляхове роздавання рідини.

“…For example, portable UFM are beneficial to use at water supply facilities where there are many individual water intake wells , or industrial water users (Cherniuk et al, 2019). At such objects, as a rule, there are no ideal conditions for the direct section of the pipeline, so it may be useful to make a corresponding correction of the results of the UFM measurement.…”

The accuracy of water flow rate measurement with an ultrasonic flow meter (UFM) is affected by pipeline conditions. On water pipelines, there is often no the required length of direct section, required by the device passport or regulatory documents. Therefore, we conducted experiments using UFM to measure water flow rate in the zone of influence of non-direct sections of the water pipeline. The flow rate was measured in two planes of the pipeline with an offset of 90 o and the average value was taken. Thus, it was expected to take into account the average water velocity for the asymmetric velocity profile. The results of water flow rate measuring with UFM on short direct sections of the water pipeline, limited by pipeline bends sudden constriction of the pipeline, are presented. The greatest influence on the UFM measurement error is the 90 o pipeline bends.

“…In recent decades, humanity has faced two conflicting energy problems. On the one hand, this is ensuring the reliability of energy supply, and on the other hand, the prevention of negative effects of energy production on the environment, both in areas where the sources of generation are located and on a global scale [BABAK et al 2020;BOSAK et al 2019;CHERNIUK et al 2020;PROKOPENKO et al 2017].…”

The impact of wind power plants on the environmental components is assessed taking into account a number of their parameters, in particular the technical characteristics of wind turbines, the characteristics of networks, engineering and other structures. To do this the life cycle of the wind power plants is described taking into account (by way of inventory) all the necessary materials and resources. Waste management scenarios have been developed, the use of which will make it possible to reduce the harmful impact on the environment. Based on the inventory and input data on the wind farm under study, a diagram is generated -a tree of life cycle processes of the wind power plant -to determine the potential environmental impacts. A list of impact categories that represent the load on the environment caused by the wind power plant is defined; also, the relative contribution of harmful factors is determined for each category, taking into account possible scenarios of waste management. Ecological profiles have been built for all potential impacts on the environment. After normalisation and determination of significance, individual estimates of all indicators and their distribution in three categories of lesions were obtained: human health, ecosystem quality and resources, as well as four stages of the wind farm life cycle: production, dismantling and disposal, operation, transportation and installation. The obtained profiles made it possible to determine individual indicators and eco-indicators, expressed in eco-points that characterise the wind farm under study.
