Particle response time formula is valid under stokes regime right, meaning particle Reynolds number is 0. But when particle flows under the influence of air flow, its Reynolds no. will never be 0 right. Can we still use this formula. Or am I understanding this wrong, other way round of thinking this formula is initial Reynolds no. of particle should be zero meaning particle should be at rest before coming under the influence of air flow. Please explain. Thanks
