Instructions: Show your entire solution. Indicate which table from the steam tables you utilized in your solution. 41.149 kg per second of water at 0.03398675 kbarg and internal energy of 15000 kW is heated at constant pressure to saturated vapor and further heated at constant volume process until the pressure is quadrupled. Determine the ratio of the heat added during the constant volume process to the heat added during the constant pressure process.

b) As shown in Figure A2-b, an insulated rigid container holds 1.4 kg of saturated water and air. At the initial state, the temperature of the saturated water is 210°C and 75% of the volume is occupied by air and the rest by the saturated liquid. An electric heater inside the container heats the water and converts to saturated vapor after 0.333 hours. Air Water 1.4kg, 210°C Figure PLEASE TURN OVER (i) Determine the volume of the container in m³. (ii) Determine the temperature of the saturated vapor (iii) Determine the power of the resistor

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.)

2) Two glass bulbs, one on the left with a volume of 2 liters and the other on the right with avolume of 6 liters, are connected to one another by a thin tube that is initially closed by astopcock. The bulb on the left has 0.1 moles of ideal gas, and the bulb on the right isevacuated. The system is in thermal equilibrium with the surroundings at 300K. When thestopcock is opened, the gas flows out to fill both bulbs. Calculate A for this process. If wewere to insert a propeller to extract work as the gas flows from left to right, what is themaximum amount of work that we could possibly extract?
