Equations for specific volume
WebAug 23, 2024 · The Clausius-Clapeyron equation then takes the form For most substances, the specific volume of the liquid ( V2) is greater than the specific volume of the solid ( V1 ); but for H 2 O, Bi and Ga, V2 < V1 and dT / dP is negative. Example: For the ice-water system, Hence That’s about −7.4 × 10 −3 kelvins per atmosphere WebTo solve this problem, it is necessary to choose a system and then apply mass and energy balances. The system is the valve. The mass flow is steady, so that the mass balance is: where. m = mass flowrate [kg/s] A = …
