Water Resistance

Can anyone explain to me how much resistance water creates while swimming? Is there a equivalent in pounds? or is there another way it is measured? If found a site that explains fluid dynamics, but I'm looking for a simpler explanation.

    And that is why streamlining is so important. Using 0.5 for the drag coefficient was a total guess, by the way. A swimmer in a good streamline probably has a lower drag coefficient than that. I would guess so. Even bad swimmer might. A 150 lbs swimmer pushes off the wall at 15 ft/sec and 25 lbs resistance would stop him in 7.5 yards That's with the silly over simplification that the drag doesn't change with speed. I could probably do the caluculus with the drag coeeficients and all, but I'm WAY too lazy. Where's that 17 year old college junior?
