Aplane wall of thickness 0.2 m and thermal conductivity 30 w/m middot k having uniform volumetric heat generation of 0.4 mw/m^3 is insulated on one side, while the other side is exposed to a fluid at 92 degree c. the convection heat transfer coefficient between the wall and the fluid is 400 w/m^2 middot k. determine the maximum temperature in the wall. ans: t_0 = 519 c

Give heat transfer applications for the following, (i) gas turbines (propulsion) ) gas turbines (power generation). (iii) steam turbines. (iv) combined heat and power (chp). (v) automotive engines

Ajournal bearing has a journal diameter of 3.250 in with a unilateral tolerance of 20.003 in. the bushing bore has a diameter of 3.256 in and a unilateral tolerance of 0.004 in. the bushing is 2.8 in long and supports a 700-lbf load. the journal speed is 900 rev/min. find the minimum oil film thickness and the maximum film pressure for both sae 20 and sae 20w-30 lubricants, for the tightest assembly if the operating film temperature is 160°f. a computer code is appropriate for solving this problem.
