Question: question f3 a thin plate of thickness t is extended...

Question details

Question F-3)- A thin plate of thickness t is extended between two walls that are at constant temperatures of Tbl and Tb2 shown in the figure below. Two different fluids, at free stream temperatures of T.i and T2 are moving on the top and bottom of the plate with convective heat transfer coefficients of h and h h,o T. bl T, b2 h, T a) Write the energy balance for a typical infinitesimal control volume (c.v.) to derive a differential equation for the temperature distribution T(x) in the plate. Solve the differential equation and apply appropriate boundary conditions to determine the temperature profile in terms of X,Tbl, Tb2, L, t, T ,T,2 h, b2 and kplate. b) calculate the rate of heat transfer per unit depth (normal to the paper) from each wall to the fin and total rate of heat transfer to the fluids for the following numerical values: Tbi-450 K, Th 0.2 m, t-3 mm, T.-250 K, T-200 K, h-8 W/mK, h-12 W/mK, bopan 120 W/m.Hk c) Calculate the fin efficiency for this plate if TTTand h- h2 10 W/m K late -
