Research and programming calculation of the relationship between pipe pressure loss and flow rate

Through analysing the application scope of the formula Δp=SQ2, indicates that the formula is not suitable for the indoor heating pipeline. By analogy with the electric circuit, provides the effective algorithm for calculating the outdoor or indoor heating pipeline respectively. Applies the programming calculation to the indoor reversed heating pipeline and obtains the influence patterns of variation of pressure loss in each section of pipeline on both the flow rate in the section and the total flow rate of the system.
