An agitator is running at 154 rpm of any agitated vessel such that the flow region of Reynolds number lies in the laminar flow region. Power requirement in such condition for the vessel is 87 W. If the speed changes to 196 rpm while the diameter of the agitated vessel, viscosity, and density of the fluid are kept without any changes, then what will be the power requirement in W?
