A thin long circular pipe of 10 mm diameter has porous walls and spins at 60 rpm about its own axis. Fluid
is pumped out of the pipe such that it emerges radially relative to the pipe surface at a velocity of 1 m/s.
[Neglect the effect of gravity.]
The percentage change in the maximum shear stress, if diameter is doubled, while keeping thickness constant, is
The percentage change in the maximum shear stress, if diameter is doubled, while keeping thickness constant, is
