For an application where the Reynolds number is to be kept constant, a liquid with a density of 1 g cm-3 and viscosity 0.01 Poise results in a characteristic speed of 1 cms-1.
If this liquid is replaced by another with a density of 1.25 g cm-3 and viscosity of 0.015 Poise, the characteristic velocity will be ______ cms-1 (rounded off to one decimal place).
Assume the characteristic length of the flow to be the same in both cases.
