injectionPressure

The injection pressure, in Pascal, is used to re-scale the injectionPressureProfile so that the integrated value equals this value.

Injection velocity profile will then be calculated based on

$U = \sqrt{\frac{2(P_{inj}-P_{amb})}{\rho}}$

where $P_{amb}$ is the averaged pressure in the computational domain. Since the ambient pressure can vary over time, this needs to be updated every time-step. It's also not possible to calculate a proper average injection velocity since the ambient pressure is unknown during the injection period at the start of the calculation.
