FlowDivider

Reduces the flow from port_a to port_b by n. Useful for modeling parallel tubes efficiently by placing a FlowDivider on each end of a tube. Extra flow is dumped into an open port.

Usage

FlowDivider(n)

Parameters:

Name	Description	Units	Default value
n	Divide flow from port_a to port_b by n	–

Connectors

• port_a - (Port)

• port_b - (Port)

• open - (Port)

Variables

Name	Description	Units
m_flow_a	Mass flow of port_a	kg/s
m_flow_b	Mass flow of port_b	kg/s
