a cylindrical rod at initial temperature ti is submerged in a constant-temperature bath at temperature tbath. the rod is 2 cm long and 0.5 cm in diameter. the rod has a thermal diffusivity of 0.0082 cm2/s. the experimental setup and transient temperature response of the rod are shown below. what is the biot number of the cylindrical rod?

as technology advances, new experiments often expose problems in accepted theories. c
