In the production of sheet metals or plastics, it is customary to cool the material before it leaves the production process for storage or shipment
In thermo mechanical data storage, a processing head, consisting of M heated cantilevers, is used to write data onto an underlying polymer storage medium.
In the spring, concrete surfaces such as sidewalks and driveways are sometimes very wet in the morning, even when it has not rained during the night.
It is desired to estimate the effectiveness of a horizontal, straight fin of rectangular cross section when applied to a surface operating at 45°C
It is common practice to recover waste heat from an oil-or gas-fired furnace by using the exhaust gases to preheat the combustion air.
Consider a 200-mm-thick solid slab of steel (p = 7800 kg/m3, c = 700 J/kg · K. k = 30 W/m · K), initially at a uniform temperature of Ti = 1400°C.
It is proposed to air-cool the cylinders of a combustion chamber by joining an aluminum casing with annular fins (k = 240 W/m · K) to the cylinder wall
It is proposed that the exhaust gas from a diesel powered electric generation plant be used to generate steam in a shell-and-tube heat exchanger with one shell
It is known that on clear nights a thin layer of water on the ground will freeze before the air temperature drops below 0°C.
In the first stage of a paper drying process, a cylinder of diameter 0.15 m is covered by moisture-soaked paper.
In the final stages of production, a pharmaceutical is sterilized by heating it from 25 to 75°C as it moves at 0.2 m/s through a straight thin-walled stainless
In the design of buildings, energy conservation requirements dictate that the exterior surface area, A" be minimized.
It has been demonstrated experimentally that the critical heat flux is highly dependent on pressure, primarily through the pressure

We assumed that, whenever fins are attached to a base material, the base temperature is unchanged.
In an extrusion process, copper wire emerges from the extruder at a velocity V e and is cooled by convection heat transfer to air in cross flow over the wire
In open heart surgery under hypothermic conditions, the patient's blood is cooled before the surgery and re-warmed afterward.
In heat treating to harden steel ban bearings (c = 500 J/kg · K p = 7800 kg/m3, k = 50 W/m · K), it is desirable to increase the surface temperature for a short
