Arod having a diameter of 2 cm and a length of 10cm has one end maintained at 200°c and is exposed to a convection environment at 25°c with h = 40 w/m2 k. the rod generates heat internally at a rate of 50 mw/m3 and the thermal conductivity of the rod is k 35 w/m k. (a) derive the nodal equation for node 3, using symbols for h, k, ax, d and q (b) -substitute numerical values for each of the given quantities and obtain an expression for the unknown nodal tem- perature t3.

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.
