QUESTION - 3 A nickel steel rod 8 cm outer diameterorginally at a temperature of 300 Troc is suddenly immersed in a liquid at 100^oc for which the convective heat transfer co efficient is 100 w/m^{2 0}k . what is the time required for the rod to reach a temperature of 150^oc ? (hint - calculate the biot number ad make the necessary assumption ).

Properties of nickel steel k = 80 w/mk
? = density =8000 kg/m³
Cp = 0.5 kj/kg ok
