If temperature affects the viscosity of the water/fluid does it also affect the speed of an object through it because as the passage through a fluid becomes easier through lessening viscosity the means of propulsion should degrade at the same rate as it relies on newtons 2nd law to move forward. So for example for a swimmer in a pool would they swim identical times if they expended identical amounts of energy at different water temps or is there a variance.Answer Question

Not sure it is really noticable with Humans swimming through it as their speed varies each time anyway.
