|| 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.
