Introduction

Natural gas is the cheapest energy carrier, so its use is widely used in the field of consumer services of residential and public buildings, as well as in industry. In this regard, competent gas supply to consumers is a very important factor.

The implementation of the course project on gas supply of the city district will allow you to get acquainted in detail with the methods of hydraulic calculation of internal and internal gas supply systems, as well as other necessary calculations, which are an important part of the entire course "Gas supply."

The task of this work is to develop a gas supply system for a quarter of a residential microdistrict in the city of Belgorod. It is also necessary to design an in-house gas supply system for a residential building, which provides continuous gas supply to gas devices and select the equipment of the gas control station.
