It is theoretically possible to drive a water jet to pressures of, say, 7,000,000 psi using explosives with a high detonation velocity, the shaped charge effect and a single use device. Higher pressures may well be possible with money, effort and optimization, for example swapping the RDX-based explosives in common shaped charges (detonation velocity around ...

RPM is just another way to say ${min^{-1}}$ so to make your equations dimensionless while still using RPM you need to convert your other measurements using seconds to minutes.
For the head coefficient
$c_h=\dfrac{gH}{N^2D^2}$
this means you need to convert $g$ from $m.s^{-2}$ to $m.min^{-2}$ (in other words multiply by 3600)
For the volume coefficient
$c_q= \...
