Chapter 7, Problem 7.12

(choose chapter or problem)

Cool water at 15°C is throttled from 5(atm) to 1(atm), as in a kitchen faucet. What is the temperature change of the water? What is the lost work per kilogram of water for this everyday household happening? At 15°C and 1(atm), the volume expansivity β for liquid water is about \(1.5 × 10^{−4} K^{−1}\). The surroundings temperature \(T_{σ}\) is 20°C. State carefully any assumptions you make. The steam tables are a source of data.
