Freezing time for 1 cm of water

Click For Summary
SUMMARY

The discussion focuses on optimizing the freezing process for constructing a backyard skating rink in South Jersey, where fluctuating winter temperatures complicate ice formation. The user seeks to build the rink by layering water 1 mm or 1 cm at a time, aiming to freeze each layer quickly before adding the next. Key questions include the freezing time for 1 cm of water, the impact of surface area on freezing rates, and how lower temperatures affect freezing duration. The conversation highlights the need for precise calculations and environmental considerations in achieving efficient ice formation.

PREREQUISITES
  • Understanding of heat transfer principles
  • Knowledge of the freezing point of water
  • Familiarity with environmental factors affecting ice formation
  • Basic physics of phase changes
NEXT STEPS
  • Research the formula for calculating freezing time for water based on thickness
  • Investigate the effects of surface area on freezing rates
  • Explore how ambient temperature variations influence ice formation
  • Learn about insulation techniques to prevent melting during warmer temperatures
USEFUL FOR

This discussion is beneficial for DIY enthusiasts, backyard rink builders, and anyone interested in the physics of ice formation and winter sports. It provides insights into practical applications of thermal dynamics in outdoor settings.

Hey guys,

I have a question... first some backround. I am asking this question is so I can build a backyard skating rink in the fastest way possible. I live in south Jersey so winter is allot of freeze/thaw.

The common way for a backyard rink is 1) place a liner 2) fill 2-3 inches 3) let freeze.
This way, however, is tough in my climate because I would need many days of sub freezing temps to get a good slab of ice.

So...I want to build it up 1 mm or cm at a time, while the temp is right, instantly adding the next layer as soon as the previous one freezes thereby saving time.

Questions:
1) is there a set formula to figure how fast 1 cm will freeze?
2) does surface area matter ? (Im sure it does)
3) how does the time to freeze change as temp drops lower

Thanks in advance for any help.

There are way too many unknowns to solve the problem as given.

How are you going to make sure your ice doesn't melt when the temps go high?
 
I wasn't too concerned about the melting. I am just interested right now how long a cm would take. Sent from my iPhone using Physics Forums
