In hot water heating systems, the non-isothermal drop method is commonly used for hydraulic calculations. What is the principle behind hydraulic calculation using the non-isothermal drop method? Feel free to participate actively in the discussions – there are wealth rewards for everyone! ! !
The variable temperature drop method involves calculations under the condition that the temperature drops in each standpipe are not equal. First, select the appropriate pipe diameter; then calculate the flow rate in the riser based on the actual hydraulic distribution of the system. Using this flow rate, the actual temperature drop in the riser can be determined, and finally, the number of radiators can be decided.

Hydraulic calculations are carried out under the condition of unequal temperature drops; they are based on the fundamental principle of pressure equilibrium at the nodes of parallel circuits, and flow rates can be allocated as needed, which helps to reduce horizontal imbalances.
