Concept explainers

Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

1. Define the following terms:
i. Equilibrium

ii. Steady state condition

iii. Uniform condition

iv. Name the two systems considered in heat transfer analysis, and derive the energy balance for
each system.

iii. Explain the mechanism of each heat transfer mode and state the law represents each case :
i. Conduction
ii. Convection
iii. Radiation

Branch of science that deals with the stationary and moving bodies under the influence of forces.

number 1 A food product containing 82% moisture content is being frozen. Estimate the specific heat of the product at -8 ° C when 82% of the water is frozen. The specific heat of the dry product is 2.5 kJ / (kg ° C). It is assumed that the specific heat of water at -10 ° C is the same as the specific heat of water at 0 ° C, and that the specific heat of ice follows the function Cp es = 0.0062 T Frozen + 2.0649. Cp of frozen product = kJ / kg ° C.
