Results
The Results:
1. Even after concluding the batch It is possible to save the successful by good management calculation in the transfer material process to a final container or to the next step
2. Evaluate the actual facility according to the new process in the pipe line too.
ExampleExample
The task: to build a temporary pipeline in order to transfer a batch of shampoo from a flat-bottom 4 cub.m. mixing tank to feeding container of filling machine.
The program VisiMix PL is used for evaluation of the minimum duration of the transfer.

ExampleExampleCharacteristics of the tank and pipeline
ExampleExample
ExampleExample
Enter the internal dimensions ofthe selected tank accordingly to the initial data above - Inside diameter, Volumeof media and Internal pressure. The Level of media will be calculated by theprogram and entered automatically.
ExampleExampleFirst Step – Adding a reactor characterization in data base equipment
Accordingly to the Table 1, in our case the before-pump part of pipeline consists of a 2 inch pipe connected to the tank outlet and 1 ½ inch pipe connected to the pump inlet. When the first input table arrives,click Add and enter the 2 inch pipe data as a ‘smooth’ pipe.
ExampleExample
The input dialog box FITTINGS AFTER PUMP is displayed automatically
ExampleExample
After the FITTINGS AFTER PUMP dialog box has been closed, the program displays a table for entering additional pipeline data and parameters of the pump. Enter the data accordingly to the Table 3 and characteristics of the pump.
ExampleExample
After these data have been entered, you are asked to enter average properties ofmedia. Order of input is the same as in other VisiMix programs. On the first stage, density of liquid is entered, and its rheological type is defined. On the next step, viscosity of Newtonian liquid or rheological constants of a non-Newtonian media are entered.
ExampleExample
In order to perform calculations, click Calculate in the main menu and selectPipeline calculation>Total transportation time
Calculated characteristics of the pipeline.
ExampleExample
Calculation of pressure drop via Last menu>Flow resistance vs. time – supply side and Last menu>Flow resistance vs. time – pumping side
The next step
ExampleExample
Analysis of the results
As follows from the data, transfer of shampoo can be performed within reasonable time - less then 20 min. However, the maximum pressure in the pipeline section after pump will be relatively high – about 3.8 Bar. Accordingly to handbook data, the maximum for riffled PVC 1 ½ in hoses can be about 3 Bar.
As the first step, in order to find the best way to reduce the pressure, click Last menu and select menu option Max. local pressure drop (bottle neck) – pumping side.
ExampleExample
Correction of the input and calculations
Result of calculation shows that pressure in the pumping line is so high due to high hydraulic resistance of the hose. One of the obvious ways to reduce the pressure – to use a hose of bigger diameter.
ExampleExample
Correction of the input and calculations
Standard diameters of riffled hoses can be found in the database of the program VisiMix PL. Select Calculate in the main menu and click Standard diameters of tubes>Riffled hoses
ExampleExample
Correction of the input and calculations
So, let us enter the 2 in. hose instead the 1 ½ in. one. Click Edit>Pipes after pump . The corresponding dialog box arrives on the screen
ExampleExample
In order to connect the hose to the pump outlet and the feeding container inlet tube (1 ½ in each), we have to enter additional elements – expander and reducer.Click Edit input>Fittings after pump
Correction of the input and calculations
Correction of the input and calculations
ExampleExample
As it follows from the results:
-Duration of transfer of the batch does not change, because the flow rate is limited by flow resistance of the supplying section of pipeline
- Maximum pressure in the pumping section of pipeline drops down toacceptable level.
