Stored Water Volume at Variant Temperatures and supply at set temperature how does this increase volume Could some one help me with a formula to solve this question
If I have stored volume of 750L at 60Deg C water in an insulated storage vessel and I increase this set temperature to 75 Deg c, How much more will I increase my stored volume of 60 Deg C.
I would appreciate a simple laymen's formula as this is a calculation i regularly have to make at varied temperatures
Thank you
 A: $$\Delta V=\beta V \Delta T$$
Coefficient of volume expansion β(1/ºC)
For water (above 4Cº) it is 0.000210 source
For ΔΤ=+15C and V=750L you get ΔV=+2.3625 L (~0.3% increase in volume)
If it was a temperature drop ΔΤ=-15C you get ΔV=-2.3625 L (~0.3% decrease in volume)
A: One thing to watch out for: if it's a sealed container the expanded volume needs a place to go. Water has VERY low compressibility. If there is any air in the container, the air will be compressed first and the final pressure will depend on the amount of air in the container. If the amount of water expansion equals the amount of air, the pressure will basically increase by 1 atmosphere (100 kPa).
If it's a sealed container without (or only very little) air, the pressure will increase by 10s of millions of Pascal. This can be VERY dangerous.
A: According to the table in this website the volume $V$ would increase by about 1% for a 15C rise at 60C, (volume is inversely proportional to density, so do $\frac{1}{V}$).
Perhaps you could use the table to make a graph to help you quickly find the volume change for different temperatures.
