A spherical ball is moving with terminal velocity inside a liquid. Determine the relationship of rate of heat loss with the radius of ball.

Explanation

Rate of heat loss`=` power `=F xx v=6pi eta r v xx v =6 pi eta r v^(2)=6p eta r [(2)/(9)(gr^(2)(rho_(0)-rho_(l)))/(eta)]^(2)`
Rate of heat loss `alpha r^(5)`
