Question

Assume pressure (P). length (L) and velocity (V) are fundamental quantities, then the dimension of coefficient of viscosity (n) is​

Answer 1

Answer:

Force has dimensions of P times normal area. Area has the dimensions of displacement squared. Displacement has the dimensions of VT.

Therefore area has dimensions [VT]^2, and therefore:

Force has dimensions of [P [VT]^2]
