Return mass flow rate m_flow as function of pressure loss dp, i.e., m_flow = f(dp), due to wall friction |
 |
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 |
 |
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 |
