Air at a mean temperature of 50 F flows over a thin-wall 1-in. O. D. tube, 10 feet in length, which as condensing water vapor flowing inside at a pressure of 14.7 psia. Compute the heat transfer rate if the average heat transfer coefficient between the air and the tube surface is 10 Btu/(hr-ft2-F).

unlike the threaded fasteners which are used to clamp the machine members, power screws are used to transmit power. common applications of power screws are: screw jacks: to lift weight. lead screw of lathe: for axial movement of tool and its precise positioning.
