PartialWallFriction

Partial wall friction characteristic (base package of all wall friction characteristics)

Package Contents

	massFlowRate_dp Return mass flow rate m_flow as function of pressure loss dp, i.e., m_flow = f(dp), due to wall friction
	massFlowRate_dp_staticHead Return mass flow rate m_flow as function of pressure loss dp, i.e., m_flow = f(dp), due to wall friction and static head
	pressureLoss_m_flow Return pressure loss dp as function of mass flow rate m_flow, i.e., dp = f(m_flow), due to wall friction
	pressureLoss_m_flow_staticHead Return pressure loss dp as function of mass flow rate m_flow, i.e., dp = f(m_flow), due to wall friction and static head

use_mu	Value: true Type: Boolean Description: = true, if mu_a/mu_b are used in function, otherwise value is not used
use_roughness	Value: true Type: Boolean Description: = true, if roughness is used in function, otherwise value is not used
use_dp_small	Value: true Type: Boolean Description: = true, if dp_small is used in function, otherwise value is not used
use_m_flow_small	Value: true Type: Boolean Description: = true, if m_flow_small is used in function, otherwise value is not used
dp_is_zero	Value: false Type: Boolean Description: = true, if no wall friction is present, i.e., dp = 0 (function massFlowRate_dp() cannot be used)
use_Re_turbulent	Value: true Type: Boolean Description: = true, if Re_turbulent input is used in function, otherwise value is not used
