Which statement is incorrect regarding Torricelli’s law?
Torricelli’s law (v = 2gh) assumes non-viscous flow and neglects losses, not depending on viscosity or requiring turbulence. The incorrect statement is that it depends on fluid viscosity. As per NCERT, applying relevant law/formula with correct units and sign convention leads to It depends on fluid viscosity. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
