I read through it just right now, and the steps given there are very similar to the YouTube video which I watched. The guide recommended me to utilize the inlet pressure and outlet mass flow rate.

It seems like my inlet pressure is incorrect.

EDIT: I have increased my inlet pressure to 100 KPa (maximum pressure mentioned in the journal) and updated my boundary conditions. The simulation seems to be converging to a positive value in the range of NPSH=10 m. This is close to the maximum NPSHa from the journal.
