Time	Narration
00:01	Welcome to this tutorial on Creating a Material Stream in DWSIM.
00:07	In this tutorial, we will learn to:
00:10	Select Chemical compounds
00:13	Define a Thermodynamic package
00:16	Choose Units and Values and
00:19	Specify a Material stream
00:22	This tutorial is recorded using DWSIM version 5. 8 (Classic UI) Update 3 and Windows 10 OS
00:32	But, this process is identical in Linux, Mac OS X or FOSSEE OS on ARM.
00:40	You should have DWSIM installed on your machine.
00:44	Let us start by creating a new steady state simulation.
00:48	To open DWSIM, go to the Desktop.
00:52	Right-click on DWSIM and click Run as Administrator.
00:59	DWSIM window opens.
01:02	Close the Tasks window.
01:05	Go to File menu and select New Steady-state Simulation.
01:11	Simulation Configuration Wizard window opens.
01:15	Click on the Next button at the bottom of the window.
01:20	First, we will add the compounds.
01:23	In the Compounds Search tab, type Benzene.
01:28	Select Benzene from ChemSep database.
01:32	Under Added column, check the checkbox for Benzene.
01:37	We can also double-click anywhere on this line.
01:41	Similarly, add Toluene from ChemSep database.
01:46	Then click on Next button at the bottom to continue.
01:52	The Property Packages window opens.
01:56	As Benzene and Toluene form an ideal solution, we can choose Raoult's law.
02:02	From Available Property Packages list, double-click on Raoult’s Law.
02:09	Now click on the Next button at the bottom.
02:13	Next option is System of Units.
02:17	Under System of Units, we will select CGS.
02:22	Then click on the Finish button at the bottom.
02:27	Let us maximize the Simulation window.
02:30	The canvas at the centre is used to create the flowsheets.
02:35	We will now create a material stream.
02:38	At the bottom of the main simulation window, we can see an Object Palette.
02:43	It has a large collection of many useful chemical engineering objects.
02:48	Go to Streams tab.
02:50	From the displayed list, drag and drop a material stream to the flowsheet.
02:56	Let us arrange the stream.
02:59	Click on the material stream named as MSTR-000.
03:04	DWSIM has given the name MSTR-000 to this stream automatically. Let me change it.
03:13	On the left hand side of the flowsheet we can see the Property Editor Window.
03:18	Under General Info, type the Object as Inlet1. Press Enter.
03:25	We can see the name Inlet1 appearing below this stream in the flowsheet.
03:31	Now let us specify the feed stream compositions.
03:35	Under Input Data, click on Compound Amounts tab.
03:40	Choose the Basis as Mole Fractions, if not already selected.
03:45	By default, Mole Fractions is selected as Basis.
03:50	Now for Benzene, enter the Amount as 0.4 and press Enter.
03:58	For Toluene, enter 0.6 and press Enter.
04:04	On the right, click on Accept Changes button.
04:09	The total of the mole fractions appears on the right hand side.
04:14	If the total is not 1, DWSIM normalises the entries, so that the total becomes 1.
04:21	Now we will specify the Feed stream properties.
04:25	The Input Data tab shows all the properties of the stream.
04:30	DWSIM assigns default values to all properties.
04:34	Go to Input Data.
04:37	Under Stream Conditions tab, select Flash Spec as Temperature and Pressure (TP) if not already selected.
04:46	By default, Temperature and Pressure should already be selected as Flash Spec.
04:52	Change Temperature to 30 degree Centigrade and press Enter.
04:58	Change Pressure to 1 atmosphere and press Enter.
05:04	Change Molar Flow to 100 mol per second and press Enter.
05:10	Let us now save this file using the Save As option.
05:15	I will save it as stream.
05:19	Close the Property Editor Window.
05:22	We can always get back to the previous pop-up by double-clicking on the stream.
05:28	We will build on this material stream in the upcoming tutorials.
05:33	Let me go back to the slides.
05:36	Let's summarize.
05:38	In this tutorial, we have learnt to
05:40	Select Chemical compounds
05:43	Define a Thermodynamic package
05:46	Choose Units and Values and
05:49	Specify a material stream
05:52	Here are some assignments for you.
05:55	Choose Benzene and Toluene mole fractions that do not add up to 1.
06:00	Check how DWSIM normalises when you press Accept Changes button.
06:05	Go to the page where you defined mole fractions.
06:10	Check what the Normalize button does when the Total is not 1.
06:15	Go to the page where we defined the molar flow rate.
06:19	DWSIM automatically displays equivalent flow rates in other units.
06:25	Check if these values are consistent.
06:29	Create a stream consisting of Benzene, Toluene and Xylene.
06:35	Carry out the previous assignments for this stream also.
06:40	This brings us to the end of this tutorial.
06:44	Watch the video available at the following link. It summarizes the Spoken Tutorial project.
06:52	The Spoken Tutorial Project Team conducts workshops and gives certificates. For more details, please write to us.
07:02	Please post your times queries in this forum.
07:06	The FOSSEE team coordinates conversion of existing flowsheets into DWSIM.
07:12	We give honorarium and certificates for those who do this. For more details, please visit this site.
07:21	The FOSSEE team helps migrate commercial simulator labs to DWSIM.
07:27	We give honorarium and certificates for those who do this.
07:32	For more details, please visit this site
07:36	Spoken Tutorial and FOSSEE projects are funded by NMEICT, MHRD, Government of India.
07:45	We thank the DWSIM team for making it as an open source software.
07:51	This tutorial was originally recorded by Prof Kannan Moudgalya in May 2015. This is Kaushik Datta from IIT Bombay. Thanks for joining.
