WHAT IS THE EXPANSION RATE OF WATER?

What do you mean by "expansion rate"? Are you referring to how long it would take water to freeze?

expansion rate

what is the expansion rate when water is heated

Mike T., Swampeast MO

Water has the least volume at 39.2F and has a volume of about 0.01602 cubic feet per pound. 100# would occupy 1.602 cubic feet.

When heated to 180F, water has a volume of about 0.01651 cubic feet per pound. 100# would occupy about 1.651 cubic feet. So, between 39.2F and 180F, 100# of water has expanded by about 0.049 cubic feet or about 0.03%

As you see there is very little expansion, but such expansion is a virtually irresistable force--that's why hot water systems must have an expansion/compression tank.

The expansion rate is not linear, so for precise work at other temps you really need to consult tables.
