An open, rigid-walled, cylindrical tank contains $4 \mathrm{ft}^{3}$ of water at $40^{\circ} \mathrm{F}$. Over a 24 -hour period of time the water temperature varies from 40 to $90^{\circ} \mathrm{F}$. Make use of the data in Appendix $\mathrm{B}$ to determine how mach the volume of water will change. For a tank diameter of $2 \mathrm{ft}$, would the corresponding change in water depth be very noticeable? Explain.

Key Concepts

Thermal Expansion

Thermal expansion describes the tendency of a fluid or solid to change its volume in response to a change in temperature. In fluids like water, an increase in temperature generally causes a decrease in density and an increase in volume. This concept is fundamental in understanding how temperature variations can affect measurements and behaviors of substances in various contexts.

Coefficient of Thermal Expansion

The coefficient of thermal expansion quantifies the rate at which a material expands per unit increase in temperature. For liquids, this coefficient can vary significantly with temperature, and knowing its value for water is essential when predicting the changes in volume as temperature changes. This coefficient is a key parameter in many engineering and physical calculations involving thermal effects.

Volume Change Analysis

Volume change analysis involves computing the change in volume due to temperature changes using the initial volume and the coefficient of thermal expansion. Understanding this concept allows one to predict how much the volume of a fluid will increase or decrease with a given temperature change, which is crucial in systems where precise volume measurements are critical.

Effects of Container Geometry

The geometry of a container, such as a cylindrical tank, plays a significant role in how volume changes translate to observable changes in the fluid's depth or height. Given a fixed cross-sectional area, even small volume changes may or may not lead to noticeable changes in depth. This concept is important in practical applications to determine whether thermal expansion will have a significant impact on system performance or measurements.
