To determine the size of the duct constant pressure method, static pressure regain method, total pressure method, velocity method. Generally uses constant pressure method. This constant pressure method is how to determine the duct dimensions using the same value per 1 m on all duct friction loss. Usually determined by flow diagrams or duct design for slide rules. You can easily determine the duct by using this program.

Besides displaying live pressure and temperature readings, the app tracks MIN/AVG/MAX pressure statistics, displays vapor and liquid saturation temperatures, calculates superheat and subcooling, calculates target superheat, and allows the user to enter and display a target subcooling value.
Converts pressure and temperature readings to your favorite units of measure, corrects for your elevation using GPS, and can be used with any one of 98 refrigerant profiles built into the app.
Enter information about each job location and each piece of equipment at that location. Screenshots taken on the job will be stored by location and equipment with a date and time stamp for each.

The "HVAC RefCharge" app is an HVAC refrigerant charging calculator that allows HVAC technicians to perform superheat and subcool refrigerant charge calculations on-the-fly. This app includes pressure/temperature data for over 75 refrigerants.
The "HVAC PT Chart" is an electronic pressure-temperature calculator that allows HVAC technicians and contractors to quickly lookup the temperature and corresponding pressure for 75 common HVAC refrigerants.
The "HVAC Duct Sizer" module allows you to perform quick and simple duct sizing analysis. You can specify the total airflow in CFM (or L/s), the aspect ratio and one of either the velocity of air or the friction loss per 100 feet (30 meters). The results include both the exact and rounded height and width (or diameter) dimensions and the calculated velocity and friction loss. In addition, you can calculate for a range of duct sizes by specifying minimum and maximum friction loss and airflow values.
The "HVAC Quick Load" module allows you to quickly calculate total heating and cooling loads for a wide variety of building types.
The "Psychrometrics" module allows you to easily perform single-state HVAC psychrometric calculations for up to 23 different combinations of input parameters.
The "Steam Tables" module allows you to calculate the properties of saturated or superheated steam by specifying 2 input properties. This module is also part of the "Pipe Sizer - Steam" module discussed below.
The "Pipe Sizer - Liquid" module allows you to size a pipe run for many different types of liquids (or fluids), pipe material and fitting types.
The "Pipe Sizer - Steam" module allows you to size a steam pipe run, and it also includes a bonus steam table calculator.
The "Pipe Sizer - Gas" module includes both low and high pressure gas pipe sizing, and it allows you to quickly size a simple low (less than or equal to 1.5 psi) and high (greater than 1.5 psi) pressure gas piping system by inputting a number of piping and gas properties.
The "HVAC Toolkit" application includes all of the great features of the individual HVAC apps such as the use of slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. It also allows you to specify different types of liquids, gases, pipe material types, duct material types, fitting quantities, min and max ranges, and step values.
All values can be displayed in English (IP) and Metric (SI) units.
In addition, all of the modules include email capabilities allowing you to email inputs and results to yourself and others.
The "HVAC Toolkit" application was designed by Carmel Software Corporation, a leader in HVAC design software since 1995. In fact, Autodesk (the makers of AutoCAD) acquired our load calculation software and incorporated it into their leading 3D modeling software called Revit. In addition, Carmel developed the ASHRAE 62.1 ventilation and ASHRAE DFDB apps that are currently sold by ASHRAE, Inc.
We also offer all of the above modules as individual apps for the Android on the Google Android App store.

The content of this app is based upon the Nebraska Pumping Plant Performance Criteria (NPPPC) that is cited by irrigation design engineers worldwide (Scheusener and Sulek, 1959). Defining the original criteria involved manufacturer’s and Nebraska Tractor Test data and field evaluations of pumping installations. Since 1959, the diesel fuel standard was updated by Fischbach and Dorn, (1981).
A new pumping plant testing program is under way to update the Nebraska Pumping Plant Performance Criteria for all energy types. Average pumping plant test results conducted previously in Nebraska and elsewhere have been near 80% of the NPPPC. Tests conducted on relatively new installations in 2009 produced results that ranged from 82% for Diesel powered units to 92% for electric units. The project will continue and the update of the NPPC will be based on data collected by the UNL and other entities across the country (Kranz, 2010).
The app is funded by the University of Nebraska-Lincoln Extension in Lancaster County. The app is adapted from an Excel spreadsheet developed by Thomas Dorn, Extension Educator Emeritus, UNL Extension, available at: http://lancaster.unl.edu/ag/crops/Long_Term_Pump.xls
