Establishing standards for mechanical systems.
00:07
In a rivet project is integral to ensuring adherence to any industry standard you
00:12
may be working to and to promote consistency across any project delivery team.
00:19
This starts by reviewing the mechanical settings
00:21
of your project or project template.
00:24
Begin a new project using the mechanical default template
00:31
from the systems tab of the ribbon select the
00:33
dialog launcher found at the bottom of the eight
00:36
track panel.
00:39
The mechanical settings, dialog box is divided into two main areas, duct
00:45
and a pipe.
00:47
Let's go ahead and take a look at the key areas of both starting with duct settings.
00:54
Most of the settings in this area relate to annotation.
00:57
With the exception of air density and air dynamic viscosity
01:03
when using the duck sizing tools in rev
01:05
it
01:05
depending on the sizing method used,
01:08
a change to these values will result in
01:10
a different outcome for the calculated duck size
01:15
when creating a duct layout to prevent an arrangement that
01:18
could use a wide variety of duct fitting angles,
01:21
which can result in a costly design.
01:24
Use the options found in angles to either set an angle increment,
01:30
what to choose from a range of predefined specific angles.
01:37
The options found under conversion will need to
01:39
be considered only of using the generate layout tools
01:43
here.
01:44
The settings will determine which duct type will be used for main runs and branches,
01:49
middle elevation values
01:51
and the type and length of flex duct to be used.
01:56
The settings for rectangular,
01:58
oval and round duct will determine which sizes of duct are
02:02
available from the drop down list when creating a layout manually.
02:06
And also which duct sizes can be used when using the duct sizing tool
02:12
to avoid using a specific size. In either case, remove the corresponding check.
02:19
In this case, 4.5 inch duct will be available for the user to choose from a size list
02:25
but will not be available as an option when sizing
02:28
the duct layer automatically using the duct sizing tools.
02:33
Finally,
02:34
the user can choose which calculation method will be used to
02:38
calculate the pressure drop in a straight segment of duct.
02:42
Each calculation method incorporates parameters found within rev
02:46
it.
02:46
And are those shown in bold
02:52
pipe settings.
02:53
Angles and conversion provide similar options
02:57
to those available within duct settings
03:01
segments and sizes allows the user to review the
03:04
available pipe segments within a project or a template.
03:09
If an existing pipe segment is not required, then it can be deleted.
03:14
And if a specific piping standard is not available,
03:17
then new segments can be created,
03:21
create a new material and scheduled type
03:26
from the materials library type carbon in the search field
03:31
and select carbon steel from the list of available materials
03:37
in schedule stroke time. Enter the new description. Schedule 20
03:44
choose an existing catalog to duplicate the sizes from then select. Ok.
03:52
Finally, from the size catalog,
03:54
remove any unwanted sizes and create any
03:57
additional sizes required for the new segment.
04:03
The fluid section of the mechanical settings allows the user
04:07
to review add or delete fluids from the list.
04:11
Each of the fluids has a range of temperatures,
04:14
dynamic viscosity
04:16
and densities
04:17
which can be applied to a piping system and will have a
04:20
bearing on the outcome of any pipe sizing that is carried out
04:27
close the mechanical settings.
04:29
And from the systems tab of the ribbon,
04:31
select the pipe command and draw a short section of pipe.
04:38
Use the tab key from your keyboard to highlight the
04:41
system and then select with the left mouse button.
04:46
A review of the type properties reveals the option to
04:50
set the appropriate fluid and temperature for a pipe system.
04:56
Access the mechanical settings again,
05:00
pipe slopes can be created and deleted to assist in creating
05:05
piping layouts that are on a full such as sanitary systems
05:09
and will be available from within the sloped piping tools
05:14
select new slope and enter a value of one inch and then select OK.
05:21
The calculation area for pipe settings allows the user
05:25
to enable the analysis of closed loop piping networks
05:30
deselected. Rick
05:32
will see such networks as two separate
05:34
systems and display the properties accordingly.
05:39
As with duct work,
05:40
the user can choose the method used to calculate
05:43
pressure drop in a straight segment of pipe.
05:47
Finally,
05:48
the flow tab displays information explaining how the flow rate and subsequent
05:53
pipe sizing is achieved for domestic hot and domestic cold water systems.
06:01
Ensuring the settings are correct in the mechanical settings
06:05
is the first step towards developing a robust mechanical modeling standard.
