In an infinite slab geometry, the volume average temperature (T) can be calculated using the following equation: 5.TiTT(t)T=n=1[n(n+sinncosn)2sin2(n)exp(n2Fo)]Bi=tan If the heat transfer coefficient is assumed to be infinite and the Fourier number is to be greater than 0.2 , demonstrate that the above equation can be simplified to the following equation: TiTT(t)T=28exp(42FO) Note: Remember that [21.5708]
