Initially, a rigid tank contains 500L of water at 300°C. By volume, the tank contains60% liquid and 40% vapor. At  the bottom of the tank, as shown, a valve is opened and half of the mass of water is withdrawn which is in the  liquid phase. Heat transfer takes place such that the temperature within the tank is constant. Determine the  heat transfer in kJ required to withdraw half of its mass and maintain its temperature. (Provide Schematic Diagram if applicable)

HELP ME WITH THIS THERMODYNAMIC PROBLEM Subcooled water at the pressure of 10 MPa and temperature of 100°C is heated at a constant pressure process to the temperature 200°C. If the mass of water is 5 kg (a closed system), determine the work and heat transfer in the process: Using compressed liquid water property table. Using saturated water property table (approximation). Using incompressible substance equations (note that in an incompressible fluid, the volume does not change).

Shown in the figure, an insulated rigid tank is divided into two equal parts by a partition. Initially, one part contains an indeal gas, and the other part is evacuated. The partition is then removed, and the gas expands into the entire tank. At the initial state, the mass of the gas is m= 4.00kg, initial pressure is p1 = 600.00 kPa, initial temperature is T1 = 300.00 K. The gas constant is R = 0.2870 kJ/(kg·K). (The internal energy can be determined by the equation ΔU=m·cv·(T2-T1), where cv =  0.7180 kJ/(kg·K) is the specific heat at the constant volume.)  Calculate the final state temperature T2.__________ (K)

During processing in a steel mill, a 900 lb steel casting at 800°F is quenched by plunging it into a 550 gal oil bath, which is initially at a temperature of 100°F. After the casting cools and the oil bath warms, what is the final temperature of the two? The weight per unit volume of the oil is 7.5 lb/gal. (Express your answer using four significant figures.) T F
