Unformatted text preview: The cooling water enters at 5C and exits at 10C. Given: ( 29 ( 29 mL g juice apple K kg kJ juice apple C v 04 . 1 / ; * 7 . 2 . = = a) How long will it take the apple juice to reach 12C? (5 pts) b) At what flowrate should cooling water be supplied? (5 pts) Assume the cooling water is turned on the moment the apple juice reaches 12C. 3. A horizontal frictionless piston-and-cylinder system is subjected to 1.013 bar external pressure. The piston and cylinder do not conduct heat, but heat can be added to the steam by a heating coil. The steam has an initial temperature of 300C and enough heat is added to increase the temperature by 200C. Determine the work, heat and entropy of generation for this process. (8 pts)...
