Introduction to mechanical settings for duct and pipe standards

Access and review the key settings and options for duct and pipe standards.


00:04

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.
