Question

what is the dimensional formula for coefficient of viscosity?

Answer 1

η=F×r÷Av
f=tangential force,r=distance  between the layer , v=velocity
dimensional formula for force = M¹ L¹T⁻²
dimensional formula for area = M⁰L²T⁰
dimensional formula for distance = M⁰L¹T⁰
dimensional formula for velocity = M⁰L¹T⁻¹
η= M¹L¹T⁻²ₓ M⁰L¹T⁰÷M⁰L²T⁰ₓ M⁰L¹T⁻¹=M¹L⁻¹T⁻¹
dimensional formula for coefficient of viscosity =M¹L⁻¹T⁻¹
and SI unit of coefficient viscosityη=pascal second
hope this helps u thanku
