This is a suite of twelve apps published already are put together to facilitate as a tool for performing energy efficiency studies especially in energy intensive chemical and process industries as well as HVAC applications. Hence, this can serve as an onsite analysis tool for energy engineers, auditors and technical personnel for assessing the energy saving potential. Further it can save more than 50% in total cost of individual apps. Apps can be grouped under three different categories such as supporting apps, device apps and energy cycle apps as given below. Supporting Apps: 1. Thermo-Physical Properties (16 common industrial fluids) 2. Fluid ΔP (Fluid pressure drops in pipes and conduits) 3. Orifice flow (Measurement of flow rates in pipes) 4. Engineering unit conversion (SI to USCS unit conversion) Device Apps: 1. Boiler Fuel Efficiency (with CHP) 2. Centrifugal Pump Specification 3. Fan Specification Performance 4. Compressor Capacity Performance 5. Heat Exchanger Performance Energy Cycles 1. Rankine Cycle 2. HVAC Cooling Cycle 3. HVAC Heating Cycle Users can save all their application data pertaining to energy cycles as well as major devices (Boiler, pump, heat exchanger and fan-duct system) in a file with unique title for reviewing and monitoring individual performance time to time. Users can use either SI and USCS units for both inputs and output. Please note that CHP (Brayton) cycle is part of BoilerFE app. The screen shots shown are mainly for energy cycle (Rankine and HVAC cooling cycles) apps. Therefore, please refer App stores for all other individual app descriptions and screen shots that were already published. Additional details are also available at our web site www.flowjoule.com/download.html This application suite has all the current updates with bug fixes for devices with iOS 14.. and higher and this will be frequently updated with added features time to time.

Added refrigerant HFC R410A in place of Freon R12 which is obsolete. 2.5 07/05/2019 Updated with bug fixes for Arm7, 64 bit devices. 2.4 07/28/2018 iOS 8 compliant. Updated for iPhone 6 and iPhone 6+ with bug fixes and modifications as applied to all individual apps published already. Runs on iOS devices with iOS 6.1 and higher. 2.3 05/17/2015 Applied recent updates to individual apps with features as given below. Also applied auto-layout features to different screens for proper rendering in both 3.5 inch and 4-inch display devices. 1. Fanspec Users now can create multiple fan-duct system and save it in a file with unique title for editing and review. 2. HVAC cooling cycle Added feature to estimate cooling load under ten major categories as shown in screen shot that also can be saved with other cycle data. Additional screen shots have been provided in our web site for review. 3. HVAC heating cycle Added feature to estimate heating load with or without humidification under ten major categories. This also can be saved along with other cycle data. Additional screen shots have been provided in our web site for review. 2.2 09/26/2013 This update is mainly for 4 inch display (iPhone5) where a few unconstrained UI objects in individual apps got displaced in 4-in screen layout as they were originally placed for 320x480px devices. 2.1 09/06/2013 1. Added feature in Rankine cycle to evaluate one-pass shell and tube surface condensers for its heat transfer capacity. This would help in determining its maintenance requirement. 2. Applied corrections with bug fixes as applied to individual apps under support and device category. 3. Updated app notes and footnotes in individual apps for better clarity on some of the input and output design parameters used in the respective apps. 2.0 08/21/2013 1. Updated BoilerFE, Unit Conversion, Thermo physical prop and OrificeQ. 2. In BoilerFE, added chemical compositions for different fuel oils and enabled the combustion heat balance sheet with flue gas and stoichiometric analysis for oil fired boilers. 3. Updated for iPhone 5 with bug fixes. 1.9 07/15/2013 Unit conversion app has been updated with additional feature on conversion table. Accordingly app displays the conversion table under selected engineering unit category for a specific unit on a separate screen. Updated the HeatX app with bug fixes in performance summary display screen under USCS unit standards. 1.8 04/08/2013 Updated following Apps of this suite to enable users to save all their individual application data with unique title that can be reloaded for monitoring and review as and when needed. 1. CPspec 2. HeatX 3. BoilerFE Please refer to the modified screen shots with detailed descriptions of above individual apps in iTunes. 1.7 12/20/2012 Following 3 apps are added to the suite to perform energy cycle analysis. 1. Rankine Cycle 2. HVAC Cooling Cycle 3. HVAC Heating Cycle The above apps in addition to existing nine would be very helpful in assessing the cycle performances with respect to sizing and conversion efficiencies. App generates the generic model that can be tailored to suit individual application and also can be saved in a file for continuous reference and to monitor changes and improvement. Updated some of the individual apps to extend properties at higher temperature and pressure ranges for steam. One can conveniently access app notes of all twelve individual apps from home screen. App notes provide additional info on each app with regard to both inputs and outputs with brief descriptions and computation logic used for better clarity. 1.6 11/30/2012 Updated the Fluid DeltaP app. Added a section on valves and fittings under pipe spec that enable users to choose any valve or fitting from the generic list to determine the pressure drop. App computes the respective K-factor (resistance factor) for the given pipe schedule and nominal diameter under complete turbulence. Users can edit this value based on supplier’s data for more accurate results. Reformatted the +result screen with minor corrections. Updated the notes with governing equations. 1.5 07/23/2012 Included function to verify both inside and outside surface area of the tube-bundle. This would enable users to compute U-coefficient accordingly. Bug fixes in data input unit conversion and validation functions while working with USCS units and using gas as a fluid (other than water and steam). Updated the HeatX app notes with additional info on LMTD correction factor and U-coefficient. Bug fixes in data input unit conversion that was inadvertently applied twice affecting the performance summary when working with USCS units and gas as a fluid. 1.4 06/26/2012 Three apps of this suite have been updated. In Fluid delta-P and Orifice Flow, custom fluid properties are now can be saved as user default values. Units for small flow rates in cc/s and in^3/s also have been added to facilitate measurement in non-schedule tubes and conduits under laminar conditions. For details please refer to the individual app screen shots. In Unit Conversion app, a separate section has been added under Flow Rate category to convert gas flow rates from Slpm to Scfm and vice versa. V1.3 06/06/2012 Thermo-physical property app has been updated with a supplement table on Saturation properties of steam where users can choose either temperature or pressure as primary argument. In addition, there is a separate section on humid air to facilitate quick reference to different humid air properties that are consistent with psychrometric charts. As the atmospheric pressure changes with altitude, it would also computes properties accordingly. V1.2 05/18/2012 Updated Boiler Efficiency app with analysis of combined heat and power (CHP) for Brayton cycle. This can evaluate potential for both power and steam generation with cycle efficiencies as shown in the following screen shot. The efficiency of the CHP boiler can be computed based on actual steam generation and its potential under given Brayton cycle parameters. Also updated the liquid fuel list with fuels used in gas turbine engines for CHP analysis. 1.1 03/26/2012 1.0 03/10/2012
