Total Pressure Family of Inlet Boundary Conditions
Total pressure family of inlet boundary conditions prescribe total pressure at the inlet.
NOTE: For incompressible fluid flow, all the pressure dimensions are always
Pa, sometimes called kinematic pressure. So, all the pressures are divided by the density. Also all the mass flow rates, torques and powers are like divided by density. For incompressible fluid flow, the pressure value is always relative, not absolute (this is why the zero value is often prescribed at the outlet).
