This value is the economic life used for financial return calculations. Energy Calculator for Horizontal Piping As an aid to understanding the relationships between energy, economics, and emissions for insulated systems for horizontal pipe applications, a simple spreadsheet calculator was developed. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
Mechanical Insulation Simple Calculators: Heat transfer coefficient calculation Hi athomas, thank you very much for this information.
The computer controls the terminal asmt with program-generated instructions and questions, which prompts user response. Should you wish to use a material that is not listed, you will need to refer to the 3E Plus program.
Persons using this practice must have a knowledge of the practical application of heat transfer theory relating to thermal insulation materials and systems.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. MIC is a program to increase awareness of c6800 energy efficiency, emission reduction, economic stimulus, and other benefits of mechanical insulation in the industrial and commercial markets. Under this system, intermediate output guides the user to make programming adjustments to the input parameters as necessary.
The default value is 20 years. A similar calculator for equipment, vertical flat surfaces, also was developed. Could you please tell me where I can find this info? As an aid to understanding the relationships between energy, economics, and emissions for insulated systems for horizontal pipe applications, a simple spreadsheet calculator was developed.
You may use the drop-down box to select one of seven insulation materials: Heat transfer coefficient calculation ASTM C gives guidance on calculating surface heat transfer coefficients although the equations have two errors in them. The default value is 1 linear foot, but you may enter any length of piping run. Calculated results are displayed for a range of insulation types and thicknesses, and include surface temperature, heat flow, annual cost of fuel, installed cost, payback period, annualized rate of return, and annual CO 2 emissions.
Below are instructions and additional information for each input variable.
The moment new editions of the standards you monitor are released, changes are made, or appendixes are published, you will be alerted by email. Monitoring Standards monitoring is a free service designed for you who wish to be alerted of changes to or new editions of the standards required in your work.
The insulation materials included in this calculator were selected to be representative of some of the materials commonly used in the industry.
This cost can be substantially reduced by the use of accurate engineering data tables, or available computer analysis tools, or both. The dimensions used in Europe are the SI equivalents of American sizes based on Practice Cand each has a different designation in each country. In simple terms, the darker the surface, the more radiant heat is absorbed. I have found at the moment this formula for vertical flow of air outside a pipe.
The heat transfer coefficient for cylinders greater than 24 inches diameter can be calculated as for vertical flat plates and will consist of radiation and convection coefficients. An example using the default values for all input variables is shown in Figure 2 on page Using the drop-down box, however, you can select any pipe size from 0.
ASTM C680 – 10
Understanding that those variances exist is the reason the multiplier approach was selected. The Simple Calculators are intended to provide the user with online, at-your-fingertips, snapshot information to help answer some the most frequently asked questions about benefits and design considerations of mechanical insulation systems.
You can adjust the cost up or down by simply modifying the multiplier. Subscription – always available and updated A web subscription provides an c6880 and secure access to standards, and you are guaranteed to always have the latest edition.
You can enter any number of years. A definition of emittance is often requested. They do not address every insulation material or application conditions-thus the phrase, Simple Calculators. If unknown, it is suggested you use 1 mph for indoor and 8 mph for outdoor applications.
