    An 8 m3 batch of oil with specific heat of 2 kJ/(kg K) and density of 850kg/m3 is being heated in a steam-jacketed, agitated vessel with 1.5 m2 of heating surface. The convective heat-transfer coefficient on the oil side is 500W/(m2K), and 10,000 W/(m2K) on the steam side. If the steam temperature is 130°C and the initial temperature is 20 °C, estimate the oil temperature after 10 minutes.

    (40 pts) Shell-and-Tube Heat Exchanger to make Jell-O Cups A counter-current shell-and-tube heat exchanger is used to heat Jell-O solution (water + gelatin) using saturated steam on the shell side. Jell-O solution must be heated to at least 80 oC, poured into individual plastic cups, and then cooled to make the solid Jell-O cups. The Jell-O solution is heated with steam that enters the shell at 2.0 bar (Tsteam = 120oC) and exits as a saturated liquid. At this temperature...
