  Applications Of Heat Transfer Fundamentals In Buildings INTRODUCTION The intent of this blog is to throw light upon the various considerations that one must make in the domain of heat transfer when it comes to providing thermal solutions to a building or designing one.Building heat transfer calculations are performed for different applications like Heat loss and heat gain through the exterior envelope, conduction through exterior envelope, conduction heat transfer through basement walls and slab-on-grade floor, short-wavelength (or solar heat) transmission, absorption, and reflection for fenestration, air leakage through exterior envelopes as well as the interior partition walls, ceilings and floors, The calculations of heat transfer also depend on material or building element-related problems like cold-bridge effect, convection within porous insulation, moisture condensation due to the simultaneous flow of air, moisture, and heat.   The fact that heat transfer mechani...

Thread manufacturing Processes Introduction: A thread is a ridge of uniform cross section in the shape of a helix that is provided on the outside or inside of a cylindrical or conical surface.  Functionally fasteners are threaded to keep the component in place. Thread manufacturing is a major manufacturing activity due to the strong need for high-precision fastening devices and power transmission systems. Elements Of Screw Thread Major Diameter Minor Diameter Pitch Diameter Pitch Helix angle Thread angle Methods of Thread manufacture: Thread cutting on Lathe: The principle is to feed the tool longitudinally while the work piece is rotating to create a helical groove on a cylindrical or conical surface. Steps to follow: Selection of a cutting tool Workpiece and cutting tool mounting Establish a relation between the cutting tool's longitudinal movement and the rotation of the work piece. Thread cutting Tool feeding and thread catching  The following points highlig...
