A steel ball having a radius of 1.0 in. (25.4mm) is at a uniform temperature of 800F. It is suddenly plunged into a medium whose temperature is held constant at 250F. Assume a convective coefficient of h=2.0Btu/(hft2.F) and average physical properties as k=25Btu/(hftF),=490 Ibm/ft3, and Cp=0.11Btu/(lbmF). Calculate the total amount of heat removed up to time t=3600s. Assume Biot number63.25kJ B. 65.89kJ C. 55.89kJ D. 60.00kJ E. 57.85kJ
