A mild steel steam pipe (k=54 W/mK) has an outside diameter of 15 cm and a wall thickness of 0.7 cm. It is insulated with a 5.3 cm-thick layer of 85% magnesia insulation(k=0.073 W/mK). Superheated steam at 500 K flows through the pipe, and the inside heat transfer coefficient is 35 W/m2K. Heat is lost by convection and radiation to surroundings at 300K, and the sum of outside convection and radiation coefficients is estimated to be 8 W/m2K. Find the rate of heat loss for a 20 m length of pipe.

When using the ohmmeter function of a digital multimeter, the leads are placed in what position relative to the component being tested? a. parallel b. control c. series d. line

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.
