A rigid container contains saturated vapour at 2.0 bar. The container is cooled by -430 KJ and the pressure drops to 1 bar. Calculate the mass of water in the container in kg. Neglect kinetic and potential energy changes. Note that the reported heat transfer is negative because energy is leaving the container. Your Answer: Answer

Question
A rigid container contains saturated vapour at 2.0 bar. The container is cooled by -430 KJ and the pressure drops to 1 bar. Calculate the mass of water in the container in kg. Neglect kinetic and potential energy changes. Note that the reported heat transfer is negative because energy is leaving the container. Your Answer: Answer Hide hint for Question 3 • It is closed system • As the container is rigid, the volume and total mass will stay the same between the initial and final state. • This means that the specific volume of water will stay constant. • Use the information in the bullet above to fine the quality of the mixture at the final state. Then, use the quality to perform the energy balance.
