A 1-m³ tank contains 1-kg of liquid water, at 20°C & 101.325 kPa, is subjected to energy interactions from the following energy sources: • An electric heating element that draws 0.2 amp from a 110-V source. A stirrer that runs at 100 rpm with shaft transmitting torque of 5 N.m A candle that transfers 1.5 kW. 10 It is required that energy sources to turn off once the pressure inside tank reaches to 400 kPa. a. On T-v diagram, properly show the locations of the initial and the final states with correct state labeling on each location b. Determine: - The initial energy of the system prior to activating energy sources. The final energy of the system after energy sources are turned off. c. How long the energy sources were on? d. Determine the energy contribution of each source to the total energy transfer.
