Double Pipe Heat Exchanger

Objective: To study and evaluate the effects of hot and cold fluid flow rate and flow configurations on the rate of heat transfer through thin walled tubes. To determine the overall heat transfer coefficient for the double pipe heat exchanger for countercurrent flow and parallel (or co-current) flow. System: The heat exchanger consists of two thin wall copper tubes mounted concentrically on a panel. The flow of water through the center tube can be reversed for either countercurrent or parallel flow. The hot water flows through the center tube, and…

Aseptic Processing vs. Conventional Canning

Aseptic Processing vs. Conventional Canning Problem: 1. Canning overcooks foods, giving poor quality 2. Cans are inconvenient and unsafe Solution: Aseptic Processing Aseptic Bag vs. Can “Aseptic Processing and Packaging means the filling of a commercially sterilized cool product into presterilized containers, followed by aseptic hermetical sealing, with a presterilized closure, in an atmosphere free of microorganisms.” “Commercial Sterility of equipment… means…free of viable microorganisms having public health significance, as well as microorganisms of nonhealth significance, capable of reproducing in the food under normal nonrefrigerated conditions of storage and distribution.” “Low-acid foods means any foods, other than…

Energy Transport

Energy Transport Energy Transport Focus on Æheat transfer Heat Transfer Mechanisms: Heat Transfer Mechanisms: • Conduction • Conduction • Radiation • Radiation • Convection (mass movement of fluids) • Convection (mass movement of fluids) Conduction Conduction Conduction heat transfer occurs only when there is physical contact between bodies (systems) at different temperatures by molecular motion. Heat transfer through solid bodies is by conduction alone, whereas the heat may transfer from a solid surface to a fluid partly by conduction and partly by convection. Fourier’s Law of Thermal Conduction Fourier’s Law…
