Athick-walled tube of stainless steel having a k = 21.63 w/m∙k with dimensions of 0.0254 m id and 0.0508 m od is covered with 0.0254 m thick layer of an insulation (k = 0.2423 w/m∙k). the inside-wall temperature of the pipe is 811 k and the outside surface of the insulation is 310.8 k. for a 0.305 m length of pipe, calculate the heat loss and the temperature at the interface between the metal and the insulation.

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

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.
