After the calculation of flows in a looped pipeline distribution network is done, very often velocity of fluid in some of the pipeline branches are undersized while in other are oversized. Hence, it is necessary to perform optimization of the pipes’ diameter to fit in range of suggested values. Suggested velocities for water flow in waterworks systems are 0.75-1.5 m/s, while in the case of natural gas flow in gas-pipelines this velocity limit is increased up to20 m/s. Problem of…

In this paper is shown short particular review of the book by the same author “Natural Gas as Heating Fuel”. First criterions for decision of appending on distribution gas network or district heating system for particular part of town are determinate on conditional urban area base. These conclusions are verified on specific settlement in Belgrade and in this paper are shown results on Karaburma settlement.

This paper presents a review of the boilers according to performed seasonal efficiency. Energy Efficiency Bands are assigned, primarily based on the verified values of seasonal efficiency. In correlation with seasonal efficiency stands annual fuel consumption of a certain boiler, and consequently annual fuel costs are comparable.

Gas distributive network in settlements are usually with contours, which assure that gas is available for consumers from few different directions. By application of concept of looped network least possible number of consumers can remain without gas in the case of malfunction in some branch. But, calculation of these types of networks is much more complicated compared with branch type of network. Here is shown example of one possible way of improvement of iterative procedure during the…

Methodology for calculating Seasonal Efficiency of Domestic Gas Boilers is set by The UK Government’s Standard Assessment Procedure for Energy Rating of Dwellings. This methodology is compatible with EU Council Directive 92/42/EEC on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels. Thus calculated Seasonal Efficiency is relevant parameter for comparisons of different models of boilers.

Calculation of gas i.e. water distribution network is much more complex compared with branch-like distribution pipelines. In this paper is shown one more suitable method in comparison to modified Hardy Cross. Here shown method as well as modified Hardy Cross method are iterative methods. For balancing of network, approximately equal number of iteration are to be calculated after the here presented node-loop method as for the improved Hardy Cross. Main advantage of the node-loop method in…

Methodology for calculation of Seasonal Efficiency of Comestic Gas Boilers is set by the UK Government's Standard Assessment Procedure for Energy Rating of Dwellings. This methodology is general applicable, and can be applied in our country. This methodology is compatible with EU Council Directive 92/42/EEC on efficiency requirements for new hot-water boilers fired with liquid or gaseous fuels. Thus calculated Seasonal Efficiency is relevant parameter for comparisons of different models…

Idioma: serbio. Language: Serbian., Razlike naspram identitetu i totalitetu, i to na kriticki i nerelativisticki nacin. U prvom odeljku se pokazuje kako se moderno promisljanje razlike pretvorilo u nekriticku disperziju i vrednosni politeizam. U drugom odeljku se izlaf.e i delom podrf.ava Habermasovo i Apelovo glediSte da duhovno jedinstvo ne mote poticati ni iz metafizike ni iz religije. U treéem odeljku se kritikuje "dijalosko" resenje ovihfilozoja, a u cetvrtom preispituje postmoderna alternativa. U petom odeljku…, For Non-Relative Difference and Non-Coercive Dialogue The aim of this artícle is to show that there are reasons for affirming the difference against the ídentity in a critical and non-relatíve way. First, the author explains how the modern thinking of difference led to pluralism and relativism. Then he exposes Habermas' and Apel's thesis that "spiritual unity" cannot stem neither from metaphysics nor from religion. He criticizes their "dialogical" solution and…
