The Kelvin-Planck and Clausius statements of thermodynamics are equivalent.  In order to proof the equivalence, the process is to demonstrate that _______   A. the violation of the Clausius statement leads to the violation of the  Kelvin-Planck statement   B. the compliance of the Kelvin-Planck statement leads to the compliance  of the Clausius statement   C. the compliance of the Clausius statement leads to the compliance  of the Kelvin-Planck statement   D. the violation of the Kelvin-Planck statement leads to the violation of the Clausius statement

A 30-lb iron casting, initially at 1500°F, is quenched in a tank filled with 2121 lb of oil, initially at 80°F. The iron casting and oil can be modeled as incompressible with specific heats 0.10 Btu/lb. °R, and 0.45 Btu/lb. °R, respectively. (a) For the iron casting and oil as the system,determine the final equilibrium temperature, in °F. Ignore heat transfer between the system and its surroundings. T+= 257.4978 (b) For the iron casting and oil as the system,determine the amount of entropy produced within the tank, in Btu/°R. Ignore heat transfer between the system and its surroundings. 0 = °F i Btu/°R

This question requires the use of the extracts from the tables of thermodynamic properties supplied. Ammonia, NH3, was once a commonly used refrigerant. In a particular (very old) refrigeration plant, ammonia has a pressure of 2.9 bar and a temperature of 40 °C. What would be the specific enthalpy of the ammonia under these conditions. 1433 kJ/kg a. b. 1552 kJ/kg 135 kJ/kg O d. 1622 kJ/kg O e. 1665 kJ/kg

X Your answer is incorrect. A rigid tank whose volume is 4 m³, initially containing air at 1 bar, 295 K, is connected by a valve to a large vessel holding air at 6 bar, 295 K. The valve is opened only as long as required to fill the tank with air to a pressure of 6 bar and a temperature of 350 K. Assuming the ideal gas model for the air, determine the heat transfer between the tank contents and the surroundings, in kJ.
