Spreadsheet based calculation to model water flow in a double pipe heat exchanger

Douglas Price presents an video useful for the chemical engineering students. By undergoing this youtube video, one can learn how to make calculation through an excel based spreadsheet to model hot and cold water flow in double pipe heat exchanger.

The experimental and theoretical study of heat exchange is very vital for chemical and mechanical engineering students.

Temperature is characterized as the amount of energy that a substance contains. Heat exchangers can be applied for transmitting that energy from one substance to another. In process units, the temperature must be controlled for inward and outward streams. These streams range from either gases or liquids. Heat exchangers increase or decrease the temperature of these streams by transmitting heat to or from the stream.

The double-pipe heat exchanger refers to the most easiest types of heat exchangers. It is known as double-pipe exchanger as one fluid runs inside a pipe and the other fluid runs connecting that pipe and another pipe that encircles the first. Flow in a double-pipe heat exchanger is co-current or counter-current. There exist two flow configurations: co-current means when the flow of the two streams run in the identical direction, counter current means when the flow of the streams run in reverse directions.

FastPIPE 12 Mechanical Estimating Construction Costs

FastPIPE is high-tech automatic estimating software designed needs plumbing and mechanical contractors who need a fast and accurate tool to estimate construction costs.

The first FastPIPE system was deployed in 1995 and it has repeatedly evolved with new features and capabilities.

FastPIPE was also the first system to use interactive Windows Graphics to simplify the estimating process.

Need to build a suspended hanger Spec? Just select the components from a list and the graphical display will automatically be adjusted.

The largest, most complete catalog with over 150,000 items (piping, fittings, valves, flanges, and hangers.) Up-to-date pricing and industry-standard MCAA and PHCC labor estimates for each of the items in our catalog, allowing you to build estimates fast and accurately. Allows you to define customized specs and takeoff screens for each individual job. Includes hundreds of "built-in" HVAC and plumbing assemblies ready for use in a takeoff. Allows you to use existing jobs as templates for new jobs.

To takeoff an item, you simply select the size and appropriate pipe, valve, fitting, flange, hanger, or specialty item. Perform takeoffs directly from digital plans on your computer screen, reducing the time and costs of printing and manually marking paper copies. Designed to work with a large number of commercial digitizers available from vendors such as GTCO Calcomp, and many others. Download labor and material takeoff to a Microsoft Excel® spreadsheet for your final bid summary. Output estimates in several formats, including standard CSV, ODBC-Compliant, or even custom formats.
