A rigid, well-insulated tank contains 3 kg of a 2-phase liquid-vapor mixture of water initially at 200 kPa with a quality of 84%. A paddle wheel stirs the mixture until only saturated vapor remains in the tank.
Draw the system with any indicated work and heat transfer and choose a system boundary that only contains the water. If present, make sure you indicate the direction of the work and heat transfer.
Draw a p-v diagram that indicates the initial and final states of the system.
Find the change in specific internal energy.
Find the total amount of energy transferred to the system by work from the paddle wheel.
