Solving Water Resources Problems - Water Saving In The Republic Of Uzbekistan, Rustam Muxammatdjanovich Raximov
Technical science and innovation
In this article we will talk about the problems of water resources in the Republic of Uzbekistan. The problem of drinking water supply, solutions to provide drinking water to the population of Uzbekistan. The largest consumers of fresh water in Uzbekistan are farmers. Due to outdated infrastructure, 40% of water is wasted. Rising food prices and the risk of spreading disease are the first signs of water shortages that we may experience in the coming еars. Uzbekcosmos told how to solve the problem. Water is an invaluable resource used not only in the home, but also in the production and …

The article presents the principle of operation of a jet turbine with a nozzle based on the "Segner" wheel and studies its shortcomings. In order to eliminate the identified shortcomings, a guide device was developed, which is installed inside the hydraulic turbine impeller. Using the Bernoulli equations and the Zhukovsky theory, the energy parameters of a microhydroelectric power station with a developed divertor device and the water flow rate in a hydroturbine are determined. The energy parameters calculated on the basis of theoretical results are analyzed, and it is found that the efficiency of a hydroturbine increases by 10-20% depending …
