How long will it take for ice cold water to reach room temperature?
Prediction Keq
Transient Response s Approximate Solution Fo > .2 Lumped Capacitance Bi < .1
Conclusion • Cooler kept food cool for 146 hrs • Lumped capacitance • Initial response (Bi<.1) • Approximate solution • Response after some time (Fo>.2) • One term is good enough
