Batch heating is a typical operation encountered in food processing. Consider a liquid food material that has to be heated in a highly agitated vessel that is fully insulated as shown in the diagram below: T. Cailed tubing Liquid Food TI Containment 1, Insulation The liquid food is to be heated by passing a hot fluid through a coiled thin walled tube with a surface area A....

a) Develop a finite difference equation, based on an energy balance for a node on the upper-left corner of a domain, as in the figure below: Too, h Ti Ay k,q Ax Note that both the top and left surfaces are exposed to an ambient temperature of Too and require a convection boundary condition, and that there is constant heat generation per volume (q) throughout the domain. The control volume surrounding the node, on which the energy balance should be...

Ch 19 HW Relationships between Molar Heat Capacities 9 of 23 Constants The amount of heat needed to raise the temperature of 1 mole of a substance by one Celsius degree (or, equivalently, one kelvin) is called the molar heat capacity of the system, denoted by the letter C. If a small amount of heat dQ is put into n moles of a substance, and the resulting change in temperature for the system is dT, then Part A Consider an...

A 2.0 kg bar of copper is heated at atmospheric pressure so that its temperature increases from 20°C to 50°C. (a) What is the work done on the copper bar by the surrounding atmosphere? SOLUTION Conceptualize This example involves a solid, whereas the preceding two examples involved liquids and gases. For a solid, the change in volume due to thermal expansion is very small. Categorize Because the expanslon takes place at constant atmospheric pressure, we categorize the process as isobaric...
