WebbThe difference is that viscosity is not affected by the rate of shearing (such as impacted by mixing, shaking, etc.) whereas the resistance to flow is. Think of water versus mud or ketchup, or your slurry or pulp sample for that matter. Water will flow as you pour it. A pulp sample will not flow unless you shake it at least a bit.
