in the lumped capacitance model of transient conduction heat transfer, the system was assumed to be at a uniform temperature. Consider what would happen for an object cooled from an initial high temeprature by convection with a cold fluid. If the biot number was large, the temperature would change more or less quickly than the lumped capacitance model predicted? explain wht?

A man turns 35 today and wishes to provide supplemental retirement income of 2500 at the beginning of each month for life starting on his 65th birthday. Starting today, he makes monthly contributions of X to a fund for 30 years. The fund earns a nominal rate of 6% compounded monthly.
