The "HVAC Pipe Sizer - Gas Plus" application allows you to quickly size a simple low (less than or equal to 1.5 psi) and/or high (greater than 1.5 psi) pressure gas piping system by inputting a number of piping and gas properties. This application combines the functionality of our popular "HVAC Pipe Sizer - Gas Low" and "HVAC Pipe Sizer - Gas High" applications. This app is a universal app meaning that it works on both the iPhone and iPad and adjusts its screen size accordingly. For low pressure gas piping, you can specify the total gas flow in ft3/hr (m3/hr) and one of either pressure drop (in. wg or Pa), pipe internal diameter (inches) or gas velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total pipe equivalent length. If you are analyzing an existing pipe system, there is an option to input the existing pipe internal diameter and one of either pressure drop or gas velocity parameters to derive the calculated gas flow and other remaining properties. For high pressure gas piping, you can specify the total gas flow in ft3/hr (m3/hr), the upstream pressure (psig or kPa), and one of either downstream pressure (psig or kPa), pipe internal diameter (inches) or gas velocity (ft/s) parameters. The results include both the exact and nominal pipe diameters and the calculated velocity and total pipe equivalent length. If you are analyzing an existing pipe system, there is an option to input the existing pipe internal diameter, the upstream pressure, and one of either downstream pressure or gas velocity parameters to derive the calculated gas flow and other remaining properties. You can specify additional parameters such as the type of gas, various properties of the gas, the pipe material type, the total length of pipe, quantities for up to 11 different types of pipe fittings, and much more. You can also choose to display values in either english or metric units. This application includes built-in pipe fitting equivalent length and nominal pipe sizing tables for a wide variety of pipe material types and diameters. This application uses slider controls that allow you to quickly increment or decrement the input values and immediately observe the calculated results. You can also manually input exact values. This app now includes the HVAC Equipment Locator.

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, we developed a number of customized apps for ASHRAE, DNV GL, and other organizations. We also offer the following additional apps for the iPhone and iPad: 1. HVAC Residential Load Calcs for iPhone and iPad 2. HVAC Quick Load Plus 3. HVAC Quick Load 4. HVAC Toolkit 5. HVAC Pipe Sizer – Gas Low Pressure 6. HVAC Pipe Sizer - Gas High Pressure 7.

Agtrinsic is an AI platform that combines Hi-Res imagery, machine learning alerting, and an innovative disease model to alert you to what's happening on your fields to allow for proactive decision making. Automated alerting makes you aware of yield limiting factors such as weeds, low emergence, nutrient deficiencies, equipment skips, airborne pathogen detection, and more. With Agtrinsic everything you need to see is at the push of a button. You can sort your fields to show top problem fields quickly, zoom in to see detailed information on every field, along with virtual scouting. Agtrinsic also offers a full scouting program. Using AI routing, Agtrinsic ensures that the scout arrives at the field at the right time. These trips are carefully timed and selected around planting, post-herbicide, as well as pre and post fungicide applications to give you the best opportunity to make a change. Once arrived, that scout takes detailed notes, relevant pictures, and tags threats present in the field. This creates a report to be reviewed and sent to an agronomist, which is then shared with you to make timely and actionable decisions. Using machine learning classification algorithms, data is collected and analyzed against libraries for specific pathogens. As a result, we can provide high confidence counts of airborne spores for various crop diseases. Additionally, Agtrinsic’s broad scale microclimate data is monitored for various environmental conditions and is used in combination with pathogen data to give a more accurate view of disease pressure. Autonomous Airborne Pathogen Detection – Enables growers to proactively maximize yields and minimize operating costs through early detection of airborne pathogens. Broad scale disease modeling – Using advanced weather algorithms to monitor disease specific pressure over any geographical area. Crowd sourced disease modeling – Using crowd sourcing, Agtrinsic categorizes alerts, to show you where the biggest concern lies. If something is going on in your field, Agtrinsic will show it. Use Agtrinsic year-round to make informed decisions, reduce risk, improve efficiency, and maximize your ROI. Collaborate & Share - Agtrinsic is Easy to Use
