pressureLoss_m_flowReturn pressure loss dp as function of mass flow rate m_flow, i.e., dp = f(m_flow), due to wall friction |
m_flow |
Type: MassFlowRate (kg/s) Description: Mass flow rate from port_a to port_b |
---|---|
rho_a |
Type: Density (kg/m³) Description: Density at port_a |
rho_b |
Type: Density (kg/m³) Description: Density at port_b |
mu_a |
Type: DynamicViscosity (Pa·s) Description: Dynamic viscosity at port_a (dummy if use_mu = false) |
mu_b |
Type: DynamicViscosity (Pa·s) Description: Dynamic viscosity at port_b (dummy if use_mu = false) |
length |
Type: Length (m) Description: Length of pipe |

Type: Diameter (m) Description: Inner (hydraulic) diameter of pipe |
crossArea |
Default Value: pi * diameter ^ 2 / 4 Type: Area (m²) Description: Inner cross section area |
roughness |
Default Value: 2.5e-5 Type: Roughness (m) Description: Absolute roughness of pipe, with a default for a smooth steel pipe (dummy if use_roughness = false) |
m_flow_small |
Default Value: 0.01 Type: MassFlowRate (kg/s) Description: Regularization of zero flow if |m_flow| < m_flow_small (dummy if use_m_flow_small = false) |
