Water-Steam properties 对比 Steam Tables 的使用情况和统计数据

The "Steam Tables" app is the #1 selling app for quickly calculating saturated and superheated steam properties. This app is a universal app that works on both the iPhone and iPad and adjusts its screen size accordingly. Bonus: The Steam Tables app now includes our popular HVAC Equipment Locator app built right in! Click here for details about that app: http://bit.ly/1yTq539 Come see why 10000s of users world-wide have chosen our app over the competition: 1.We offer the largest combination of input parameters over all competitive apps, including: For saturated steam: Temperature and quality Temperature and enthalpy Temperature and specific volume Temperature and entropy Pressure and quality Pressure and enthalpy Pressure and spec. volume Pressure and entropy For superheated steam: Temperature and pressure Temperature and enthalpy Temperature and spec. volume Temperature and entropy Pressure and enthalpy Pressure and spec. volume Pressure and entropy 2. We display a wide range of results (see the screenshots below for a sample). 3. Using the slider controls, you can instantly view results as you update the input parameter values by moving the slider indicator. Also, you can increment/decrement by specific values for each parameter type. You can manually input exact values if so desired, too. 4. This app is not just a steam-table lookup app. It is powered by the actual steam-table formulas, so you can calculate for all ranges of input values, not just those published in steam table books. 5. All values can be displayed in both English (IP) or Metric (SI) units. Also, you can choose to display different types of units for specific parameter types such as pressure and temperature. 6. We offer comprehensive support and regular updates based upon feedback from existing users. We've been around for 15 years and plan on being around for much longer, so you can be assured that this and all of our apps will continue to be supported and updated. We also offer the following additional applications for the iPhone/iPad: 1. HVAC Duct Sizer 2. HVAC Pipe Sizer – Gas Low Pressure 3. HVAC Pipe Sizer - Gas High Pressure 4. HVAC Pipe Sizer – Liquid 5.
