| Abstract: | The new equation for friction loss along the hot water is presented using the multi-regression analysis according to existing elementary friction equation. Also, such factors as velocity of flow, pipe diameter, water temperature, etc, are taken into account in the equation, thus making calculated results adaptable to practice. Accordingly, the e-quation is considered to meet the design requirements and to be used in the design and calculation of hot water pipe through analysis. |
