'''Title Slide'''
|| Welcome to this tutorial on '''Creating a Material Stream '''in '''DWSIM.'''
|- 
|| '''Slide Number 2''' 

'''Learning Objective''' 
|| In this tutorial, we will learn to:
* Select '''Chemical''' compounds
*Define a '''Thermodynamic package'''
*Choose '''Units''' and '''Values''' and 
*Specify a '''Material stream'''
|- 
|| '''Slide Number 3''' 

'''System Requirements''' 
|| This tutorial is recorded using
*'''DWSIM version 5. 8 (Classic UI) Update 3 '''and 
*'''Windows 10 OS'''

But, this process is identical in '''Linux, Mac OS X '''or '''FOSSEE OS on ARM'''. 
|- 
|| '''Slide Number 4''' 

'''Pre-requisites''' 
|| You should have '''DWSIM''' installed on your machine.
|- 
|| 
|| Let us start by creating a new''' steady state simulation'''.
|- 
|| Cursor to '''Desktop'''

'''DWSIM''' >> '''Run as Administrator.'''
|| To open '''DWSIM''', go to the''' Desktop'''.

Right-click on '''DWSIM '''and click '''Run as Administrator.'''
|- 
|| '''DWSIM''' window opens.
|| '''DWSIM''' window opens.
|- 
|| Close the '''Tasks''' window.
|| Close the '''Tasks''' window.
|- 
|| '''File''' >> '''New Steady-state Simulation '''
|| Go to '''File''' menu and select '''New Steady-state Simulation.'''
|- 
|| Cursor to '''Simulation Configuration Wizard''' window
|| '''Simulation Configuration Wizard''' window opens.
|- 
|| Click on '''Next '''button at the bottom.
|| Click on the '''Next''' button at the bottom of the window.
|- 
|| 
|| First, we will add the compounds.
|- 
|| Type '''Benzene''' in the search tab
|| In the '''Compounds Search '''tab, type '''Benzene'''.
|- 
|| '''ChemSep Database >> Benzene'''
|| Select '''Benzene''' from '''ChemSep '''database. 
|- 
|| Point to '''Benzene''' compound 

Check the checkbox under column '''Added'''
|| Under '''Added''' column, check the checkbox for '''Benzene'''.

We can also double-click anywhere on this line.
|- 
|| Type '''Toluene '''in the search tab

|| Similarly, add '''Toluene '''from '''ChemSep database'''.

|- 
|| Click on '''Next''' button at the bottom. 
|| Then click on '''Next''' button at the bottom to continue.
|- 
|| Point to '''Property Packages'''
|| The '''Property Packages '''window opens.
|- 
|| Cursor on '''Property Packages '''window.
|| As '''Benzene''' and '''Toluene''' form an ideal solution, we can choose '''Raoult's law.'''
|- 
|| '''Property Packages''' >> '''Available Property Package'''

Double click on '''Raoult’s Law'''
|| From '''Available Property Packages''' list, double-click on '''Raoult’s Law.'''

|- 
|| Click on '''Next '''button.
|| Now click on the '''Next '''button at the bottom. 
|- 
|| Point to '''System of Units'''
|| Next option is '''System of Units.'''
|- 
|| '''System of Units >> CGS'''
|| Under '''System of Units, '''we will select '''CGS'''. 
|- 
|| Click on the''' Finish''' button.
|| Then click on the '''Finish '''button at the bottom.
|- 
||Click on Maximize button.
|| Let us maximize the '''Simulation''' window.
|- 
||Hover the mouse at the centre
|| The canvas at the centre is used to create the '''flowsheets'''.

We will now create a '''material stream'''.
|- 
|| Hover the mouse at '''Object Palette'''
|| At the bottom of the main '''simulation''' window, we can see an '''Object Palette.'''

It has a large collection of many useful '''chemical engineering objects.'''
|- 
|| Click and drag '''material stream''' to flowsheet
|| Go to '''Streams''' tab.

From the displayed list, drag and drop a '''material stream''' to the '''flowsheet'''.
|- 
||Cursor at the stream.
|| Let us arrange the '''stream'''. 
|- 
|| Click on '''MSTR-000.'''

Pop up appears.
|| Click on the '''material stream''' named as '''MSTR-000.'''

'''DWSIM''' has given the name '''MSTR-000''' to this '''stream''' automatically.

Let me change it.
|- 
|| Hover the mouse to '''Property Editor Window'''
|| On the left hand side of the '''flowsheet '''we can see the '''Property Editor Window'''.
|- 
|| Type '''Object''' as '''Inlet1.'''
|| Under '''General Info, '''type the '''Object''' as '''Inlet1.'''

Press''' Enter.'''
|- 
|| Point to the '''Material''' Stream
|| We can see the name '''Inlet1''' appearing below this '''stream''' in the '''flowsheet'''. 
|- 
|| Cursor on the interface.
|| Now let us specify the '''feed stream compositions.''' 
|- 
|| '''Input Data >> Compound Amounts '''
|| Under '''Input Data, '''click on '''Compound Amounts''' tab. 
|- 
|| '''Compound Amounts >> Basis >> Mole Fractions '''
|| Choose the '''Basis '''as '''Mole Fractions,''' if not already selected. 

By default, '''Mole Fractions''' is selected as '''Basis.''' 
|- 
|| '''Benzene: 0.4 '''
|| Now for '''Benzene''', enter the '''Amount''' as '''0.4''' and press '''Enter.''' 
|- 
|| '''Toluene: 0.6'''
|| For '''Toluene''', enter '''0.6''' and press '''Enter'''. 
|- 
|| Click '''Accept Changes'''
|| On the right, click on '''Accept Changes''' button. 
|- 
|| Hover the mouse at '''Total'''
|| The total of the '''mole fractions''' appears on the right hand side.

If the total is not '''1''', '''DWSIM '''normalises the entries, so that the total becomes '''1.'''
|- 
||Cursor on the interface.
|| Now we will specify the '''Feed stream''' properties. 
|- 
|| Point to '''Input Data'''

Cursor to the default values
|| The '''Input Data''' tab shows all the properties of the '''stream'''.

'''DWSIM '''assigns default values to all properties.
|- 
|| Click on '''Input Data. '''
|| Go to '''Input Data.'''
|- 
|| '''Stream Conditions >> Flash Spec >> Temperature and Pressure (TP)'''
|| Under '''Stream Conditions '''tab, select '''Flash Spec''' as '''Temperature and Pressure (TP)''' if not already selected.

By default, '''Temperature '''and''' Pressure '''should already be selected as '''Flash Spec.'''
|- 
|| '''Input Data >> Temperature >> 30 C '''

Press '''Enter''' 
|| Change '''Temperature''' to '''30 deg C''' and press '''Enter.''' 
|- 
|| '''Input Data >> Pressure >> 1 atm '''

Press '''Enter''' 
|| Change '''Pressure''' to '''1 atm''' and press '''Enter.''' 
|- 
|| '''Input Data >> Molar Flow >> 100 mol/s '''

Press '''Enter''' 
|| Change '''Molar Flow''' to '''100 mol/s''' and press '''Enter.''' 
|-
|| Click on '''File '''and Click '''Save As''' 
|| Let us now save this file using the '''Save As''' option. 
|- 
|| Type '''stream''' 
|| I will save it as '''stream.''' 
|- 
|| '''Close the Property Editor Window.'''
|| Close the '''Property Editor Window'''.
|- 
|| Click on the''' Material''' Stream 
|| We can always get back to the previous pop-up by double-clicking on the '''stream'''.
|- 
|| 
|| We will build on this '''material stream''' in the upcoming tutorials. 
|- 
||
||Let me go back to the slides. 
|- 
||
||Let's summarize. 
|- 
|| '''Slide Number 5'''

'''Summary'''
|| In this tutorial, we have learnt to 
*Select '''Chemical''' compounds
*Define a '''Thermodynamic package'''
*Choose '''Units''' and '''Values''' and 
*Specify a '''material stream'''
|- 
|| 
|| Here are some assignments for you.
|- 
||'''Assignment 1 Slide'''
|| Choose '''Benzene''' and '''Toluene mole fractions''' that do not add up to''' 1'''. 

Check how '''DWSIM '''normalises when you press '''Accept Changes''' button.
|- 
||'''Assignment 2 Slide'''
|| Go to the page where you defined '''mole fractions.''' 

Check what the '''Normalize''' button does when the '''Total''' is not '''1'''. 
|- 
||'''Assignment 3 Slide'''
|| Go to the page where we defined the '''molar flow rate'''. 

'''DWSIM''' automatically displays equivalent '''flow rates''' in other units. 

Check if these values are consistent. 
|- 
||'''Assignment 4 Slide'''
|| Create a '''stream''' consisting of '''Benzene, Toluene '''and '''Xylene.''' 

Carry out the previous assignments for this '''stream''' also.
|- 
||
|| This brings us to the end of this tutorial.
