Question

Many hot-water heating systems have a reservoir tank connected directly to the pipeline, so as to allow for expansion when the water becomes hot. The heating system of a house has 74.8 m of copper pipe whose inside radius is 9.23 x 10- 3 m. When the water and pipe are heated from 25.2 to 63.3 °C, what must be the minimum volume of the reservoir tank to hold the overflow of water?
