Based on water volume ?
The coefficients for pressure loss in the fittings can be found in the product catalogue. The pressure loss is calculated using the “Nikuradse” formula. The coefficients are found in the product catalogue.
This tool is only intended for assisting you with your calculations. It is not a substitute for detailed professional design.
Based on components for hot and cold water systems ?
This method is used for calculating the pipe sizes for standard installations. DIN 1988/300 is generally used for calculating the sizes in specific projects such as hospitals, health treatment centres, hotels, schools. This method is used for both hot and cold water.
Linear expansion ?
Linear expansion is determined by the length of the pipe, the increase in temperature and the coefficient of expansion. The size of the pipe is irrelevant. The force of expansion is determined by the size of the pipe and the change in temperature. The length of the pipe is irrelevant.
