A0.2-m-long and 25-mm-thick vertical plate (k=15 w/m∙k) separates the hot water from the cold water. the plate surface exposed to the hot water has a temperature of 100°c, and the temperature of the cold water is 7°c. determine the temperature of the plate surface exposed to the cold water (ts, c). hint: the ts, c has to be found iteratively. start the iteration process with an initial guess of 53.5°c for the ts, c.

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.

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above
