Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.

Question

force (or force resultant) does work, or the rate at
which a system's energy changes. In both cases,
power will have units of energy per unit time.

NASA sent a probe to Saturn's moon Titan, where the acceleration due to gravity is 1.4 meters per second squared [ms2]. Titan's atmospheric pressure is 1.3 times Earth's atmospheric pressure at sea level. The probe landed in a lake of liquid methane, which has a density of 0.454 kilograms per liter [kgL]. Since the probe weighs 300 pounds-force [lbf] on Titan and has a volume of only 1.2 cubic feet [ft3], it immediately sank. It now sits 65 feet [ft] below the surface of the lake. The lake has a surface area exposed to the atmosphere of 24500 square meters [m2]. What is the total pressure exerted on the probe, in pascals [Pa]?

To apply the principle of work and energy to a system of particles. The principle of work and energy can be extended from one particle to include a system of particles as follows: ∑T1+∑U1−2=∑T2 where ∑T1 is the system's initial kinetic energy, ∑U1−2 is the sum of the work done by all external and internal forces acting on the system's particles, and ∑T2 is the system's final kinetic energy. When the particles either are undergoing only translational motion or are connected by inextensible cables, the internal forces of the particles negate each other; only the external forces are required in the principle of work and energy. When frictional forces are present, the work done by the frictional force is UF=μkNs, where μk is the coefficient of kinetic friction, N is the normal force, and s is the body's displacement. In this equation, the work done by friction represents both the external work of friction and the internal work that is converted into various forms of internal energy, such…
