Hi,

I am starting to model a condenser water GRE piping system.
Some basic questions.
1.How to model a pump. How to set the height of the pump & a pipe connected to it.
2. How to set the elevations of the pipe from the ground. A horizontal pipe 1100 mm is on a resting support. Length 6 m.

1) Pumps are typically modeled with a series of rigid elements. From the pipe nozzle, use a rigid element horizontally to the pump center, then another rigid element vertically down to the base. Put an anchor at the base. The pump weight should be proportioned to the rigid elements appropriately.

The height of the pump and location of the nozzle would depend on the lengths you use for the rigid elements.

2) Assuming everything in your model is connected, then setting the coordinates of the first node positions the entire model. The coordinates of the first node can be set using the [Alt+G] key combination.

Hi,

How to model a basket strainer.

guru

Small strainers are typically castings, so these could be modeled as a rigid element.

For larger strainers, you could model to the basket using the appropriate "flange-pipe" pair on both sides. However, you can't model the actual basket, so you should span this gap with a rigid. Note, CAESAR&nbspII will not provide accurate stresses on the the strainer. If this is what you're worried about, you will need to perform a local analysis based on the pipe loads that CAESAR&nbspII computes.

The basket strainer i have is 1 metre in length. So i believe i can model it as a rigid element.
