CALCULATION OF CRUDE OIL PIPELINE PARAMETERS BY NUMERICAL METHOD

Based on the fluid characteristics of hot oil pipelines the mathematical model for calculating technology parameters by numerical method is established. Within the temperature range of each fluid state the theoretical processing length and relevant parameters are calculated using the yleffoeca formula which takes friction generated heat into consideration. When the given length is shorter than theoretical length, the equations of technology calculating which are complicated are solved by dichotomy way. The program the paper presents can do 44 kinds of performance calculations.
