A plane wall of thickness 8 cm experiences uniform volumetric heat generation ( q ). One
surface of the wall is insulated, and the other surface is exposed to a fluid at T(infinite) = 20 degree with
convection heat transfer characterized by h=1000W/m2.K. The initial temperature distribution
on the wall is given as: T (x,0) = 300-0.1*10^4*X^2 , where x is in meters. Suddenly, the
volumetric heat generation is deactivated, while convection heat transfer continues to occur at
x=L. If the wall properties are 7000kg/ m^3 ,Cp= 450J/ kg. K, k=108W/ m. K
(a) Determine the magnitude of the volumetric energy generation rate q associated with the
initial condition (t < 0).
(b) Calculate heat flux at the boundary exposed to the convection process at t=0, qx (L,0)
(c) Calculate the amount of energy removed from the wall per unit area (J/m2) by the fluid
stream as the wall cools from its initial steady state condition.

Analyzing and computing accrued warranty liability and expense waymire company sells a motor that carries a 60-day unconditional warranty against product failure. from prior years' experience, waymire estimates that 2% of units sold each period will require repair at an average cost of $100 per unit. during the current period, waymire sold 69,000 units and repaired 1,000 units. (a) how much warranty expense must waymire report in its current period income statement? (b) what warranty liability related to current period sales will waymire report on its current period-end balance sheet? (hint: remember that some units were repaired in the current period.) (c) what analysis issues must we consider with respect to reported warranty liabilities?
