Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

Scenario A pipe made from martensitic steel, with inner and outer diameters of 56 mm and 60 mm, respectively, has been fixed perpendicularly to a wall, and the pipe lies along the X-axis, as presented in Fig. 1a. Two steel arms of the same length have been welded perpendicularly (along the Y-axis) to the pipe, on the same X-Y plane (Fig. 1b, view along the X-axis), and the arms are parallel to the wall (Fig. 1c, view along the Z-axis). The two arms are subjected to external vertical loading (along the Z-axis) in opposite directions with equal magnitude (Fig. 1a). The arms are made of the same material as the pipe, and they can be assumed to be rigid (no deflection within the arms). Please note the lengths and diameters of the pipe/arms in the figure are not to scale.

5.10 A flaked cereal is of thickness 2L = 1.2 mm. The density, specific heat, and thermal conductivity of the flake are p = 700 kg/m³, cp = 2400 J/kg K, and k = 0.34 W/mK, respectively. The product is to be baked by increasing its temperature from T₁ = 20°C to T, = 220°C in a convec- tion oven, through which the product is carried on a con- veyor. If the oven is L₁ = 3 m long and the convection heat transfer coefficient at the product surface and oven air temperature are h = 55 W/m² K and T. = 300°C, respectively, determine the required conveyor velocity, V. An engineer suggests that if the flake thickness is reduced to 2L = 1.0 mm the conveyor velocity can be increased, resulting in higher productivity. Determine the required conveyor velocity for the thinner flake. 2L = 1.2 mm Conveyor belt Cereal product V L₂ Oven h = 55 W/m².K T_= 300°C

Problem 3.2 A small scale wind turbine tower needs to pivot about its base because it is raised up from the ground by a gin pole. The tower is secured in the upright position by a pair of 0.25 inch diameter cables, each attached to an anchorage, as shown. The cable has a working load limit of 1200 lb (working load means it is the permitted load and includes a factor of safety relative to the cable's likely actual strength). The cables are initially tensioned by equal amounts. The thrust force from the turbine's operation is balanced by an increase in the tension in the front cable and an equal decrease in the rear cable. The rightward deflection of the tower due to the thrust force causes an elongation of the front cable that is equal to the shortening of the rear cable, which is why the magnitudes of the tension changes are equal. The pre-tension in the cables must be chosen so that neither side goes slack nor does the maximum tension exceed the load limit. Assume a steady thrust…
