To calculate the heat transfer rate the … WebA flat steel plate is 2.0 m length and 2.0 m width initially contain a very thin coating of lubricating oil used in a manufacturing process. An engineer is considering the feasibility of using hot forced air convection to remove the lubricating oil from the surface as an alternative to using harmful solvents to rinse the lubricating oil off the surface.

WebThe role played by Reynolds number in forced convection is played by the Grashof number in natural convection. The critical Grashof number is observed to be about 109 for vertical plates. Thus, the flow regime on a vertical plate becomes turbulent at Grashof number greater than 109. The heat transfer rate in natural convection is expressed by http://www.pathways.cu.edu.eg/ec/text-pdf/part%20b-8.pdf

WebThe coefficient of heat transfer by convection, h, can be obtained from the unsteady energy balance: q ˙ A = hA T aw − T w = mc d T w dt h = mc A d T w / dt T aw − T w where m is the mass of the disk, c the specific heat of the wall and dT w / dt the slope of a plot T w ( t ) obtained in the measurement ( Figure 5.11 ).
