Made a acute model of hydraulic calculation and loading time calculation for loading by gravity system according to the process feature which is that the flow rates are different in different hoses of the system.Furthermore discussed the numerical calculation method and the basic reasoning of the hydraulic calculation of the system and then got the flow rates in collecting pipeline and the hose at a certain liquid level by using hypotenuse transversal method to solve the hydraulic calculation equations of the pipeline system.And got the loading time by Romberg numerical integral method.Finally,programmed by VC++6 0 to calculate the pipeline system for the loading by gravity system through which can have quick process design calculation and operating simulation calcuation.The calculaton indicates that the more the hoses under operation are,the bigger the flow rate difference of the different hoses is.
