Does the viscosity unit "$\mathrm{ps}$" exist or is it a misprint and refers to poise "$\mathrm{P}$"? Thank you

A liquid of $0.014\,\mathrm{ps}$ viscosity and $1.4\,\mathrm{g/cm^3}$ density circulates through a $3.14\,\mathrm{cm^2}$ section pipe with a flow rate of $0.352\,\mathrm{liters/s}$. Determine the Reynolds number of the flow and decide if the liquid is flowing in laminar or turbulent regime. Sun: $Re = 22415$; turbulent regime

    $\begingroup$ As a matter of typesetting conventions, units should be set in roman type. $\endgroup$

  • $\begingroup$ Wikipedia-fu for you: viscosity#unit section leads to poise which states cps is an alternative abbreviation for centipoise which is then obvious that ps is indeed poise. $\endgroup$

The two common units for viscosity are the poise (symbol $\rm{P}$) and the Pascal second (symbol $\rm{Pa.s}$). The poise is the cgs unit while the Pascal second is the SI unit.

Given that the question appears to be using the cgs system I would guess that ps is being used as an abbreviation for poise.
