Libraries:
Simscape / Foundation Library / Gas / Sensors

Description

The Transport Properties Sensor (G) block represents an ideal sensor that measures the dynamic and kinematic viscosity, thermal conductivity, and Prandtl number in a gas network. There is no mass or energy flow through the sensor.

The block measures these properties at the node connected to port A.

Ports

Output

μ — Dynamic viscosity measurement, Pa*s
