A shape factor is a way for engineers to estimate the heat transfer in an idealized situation, usually between two temperature potentials. The temperature potentials don't change in time, so it is assumed steady state. There is no internal variation in each temperature potential. This is useful when the problem is a second order partial differential equation, and the engineer is under a time constraint.
It depends on the medium of heat transfer. For solids, it is conduction heat transfer. For liquids and gases, it is convection heat transfer. for vacuum (no medium), it is radiation heat transfer.
it is ratio of the total heat transfer from the surface area associated with both the fins and exposed portion of the base to maximum heat transfer from same surface area (in ideal conditions we get maximum heat transfer)
It is the ratio of room sensible heat to the total heat.
steam is lost in the plant through variuos way. But generally it is through heat transfer to the product to be heated by the steam. Also heat transfer through the conducting passage.

depends what kind of container and what shapes you are talking about
Fouling factor is essentially used in determining the efficiency of the heat exchangers. Fouling factor is obtained from service (product) on either side of tubes and material of tubes. It basically represents corrosion of heat exchangers tubes which affects efficiency of heat transfer.
Convection heat transfer is the transfer of heat by the movement of a fluid.
Heat inside a building warms the wall surface by convection,(the transfer of heat by fluid motion), the heat then travels through the wall by conduction (molecule by molecule heat transfer), the outer surface of the wall then gives off heat to the atmosphere again by convection. The rate of heat transfer through the wall is affected by two things: the number of films (surfaces, or boundaries) it must pass through, the more films the slower the transfer. And secondly the u factor, or insulation properties of the materials through which the heat travels.Heat inside a building warms the wall surface by convection,(the transfer of heat by fluid motion), the heat then travels through the wall by conduction (molecule by molecule heat transfer), the outer surface of the wall then gives off heat to the atmosphere again by convection.

Convection - heat transfer through liquids.Conduction - heat transfer through solids.Radiation - heat transfer through vacuum.
Convection heat transfer is the transfer of heat by the movement of a fluid.
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.

Heat will be transferred initially by conduction, which is the direct heat transfer between object (your hand and the liquid). If you leave your hand in long enough, convection will become a major factor. Convection is when currents from a liquid circulate to transfer heat.
The transfer of heat by fluid is convection.
