Question:
Repeat Problem 3.31 if the temperature distribution on the top surface of the bar varies sinusoidally from 40?C at the left edge to a maximum of 250?C in the center and back to 40?C at the right edge.From Problem 3.31: In a long, 30-cm square bar shown in the accompanying sketch, the left face is maintained at 40?C and the top face is maintained at 250?C. The right face is in contact with a fluid at 40?C through a heat transfer coefficient of 60 W/(m2K) and the bottom face is in contact with a fluid at 250?C through a heat transfer coefficient of 100 W/(m2K). If the thermal conductivity of the bar is 20 W/(mK), calculate the temperature at the 9 nodes shown in the sketch.GIVENSquare bar with one surface at fixed temperature, one surface with a specified temperature distribution, and two surfaces with convective boundaryconditions
DistributionThe word "distribution" has several meanings in the financial world, most of them pertaining to the payment of assets from a fund, account, or individual security to an investor or beneficiary. Retirement account distributions are among the most...
