A hot sphere is cooled by forced convection from its initial temperature to ambient conditions. The temperature of the sphere is calculated as a function of time. The following initial conditions are provided: Item Value Unit Description h 40 W/ K/m2 Convection heat transfer coefficient Ti 473 K Initial temperature of the sphere Too 293 K Ambient temperature D 1 cm Diameter of the sphereTT hA =expi(s)ti TiToo PVs CP 0 Calculate and show the Biot number (Bi 2 h x ch k] for your sphere following these steps: 0 Provide the surface area of the sphere (As) and include the units Provide the volume if the sphere (Vs) and include the units Provide the characteristic length of the sphere [LC] and include the units Include the convection heat transfer coefficient lh) and include the units Include the conduction heat transfer coefficient for Copper [k] and include the units . This is obtained from SolidWorks Calculate the Biot number (Bi) 0 Is Bi smaller or larger than 1? . Sh0uld the temperature variation inside the sphere be large or small? GOOD 0
