Question

An AISI 316 steel sphere (k = 12.94 W/m-K) has a diameter of 3.5 cm. The steel sphere is initially at 0 °C and is exposed to a flow of water at 30 °C, which flows at a velocity of 0.1 m/s. The sphere exchanges heat by convection with the water. Assuming that the environment behaves as a thermal reservoir and neglecting the effects of radiation, do the following: Determine the time, in seconds, for the temperature in the center of the sphere to reach 26°C.

Step 1

The surface area of a sphere can be calculated using the formula: A = 4πr^2, where r is the radius of the sphere. Since the diameter of the sphere is given as 3.5 cm, the radius can be calculated as r = 3.5 cm / 2 = 1.75 cm = 0.0175 m. Substituting this value into Show more…
