Elementary question involving turkey thaw process

[JonS356]

I hope that someone here can answer this question...

I have an 18 lb. turkey that needs to be thawed in cold water over 9 hrs., with the cold water replaced every 30 minutes.

If I use a container about 3 times the size of the sink, will that allow me to change out the water every hour and a half (3x30mins.) and get the same results? That doesn't seem right...

Thanks for your time, and Happy Thanksgiving!

Bump- Please reply! Thanks.

One more try. Looking for equation to calculate thaw time difference between sink-size and tub-size?

Here is on page 22-23 the heat diffusion equation for cooking a turkey in spherical coordinates:

Separation of variables and integrating are straight forward. But what are good values for the heat capacity and thermal conductivity for a turkey?
Thanks
