Thermo Physical Prop vs Algebra Fun

This app provides important thermo-physical property data on seventeen fluids that are very common in industrial applications. Data helps in computation of various parameters pertaining to flow system design involving heat and energy transfers. This App can become very handy for engineers and students dealing with thermodynamics, fluid mechanics and heat transfers as a quick reference guide. Fluids: Air, Steam, Water, Nitrogen, Oxygen, Hydrogen, Helium, CO2, Methane, Ethane, Chlorine, Ammonia, Argon, Hydraulic oil, HFC (R410A), Mercury, Sulfuric Acid. Properties: The property data is presented in SI and USCS units for the given pressure and temperature conditions. Property data is displayed in two parts. The first part is on transport properties that are common to all fluids and presented in home screen as shown in the screen shot. The second part is displayed as plus properties that are exclusively for gases and steam as given below. •Thermo-physical Transport properties. o Density (ρ) – function of temperature and pressure o Viscosity (μ) – function of temperature o Specific Heat (cp) – function of temperature o Thermal conductivity (K) – function of temperature •Gas properties o Molecular wt. (MW) o Specific heat ratios (cp/cv) o Thermal diffusivity (α) o Prandtl number (Pr) For steam, additional thermodynamic property data are provided in the form of a Steam Table covering all 3 states such as saturated water, saturated vapor and superheat conditions at a given pressure and temperature. Besides, a separate section is provided for saturation properties where users can choose either temperature or pressure as primary argument as shown in the screen shot. Similarly for Air, there is a section on humid air properties that are consistent with psychrometric chart. Users can choose either wet-bulb temperature or relative humidity as primary argument in addition to dry bulb temperature. The result includes humidity ratio, dew point temperature, specific volume, specific enthalpy and entropy for both dry and humid air as shown in the screen shot. In addition app notes has a link to a complete documentation on implementation and validation of math-models with industry examples. Refrigerant Freon-R12 is no longer used in any HVAC or industrial applications. Therefore it has been replaced with HFC R410A and app provides transport properties and vapor pressure data for a given saturated liquid temperature. It is often very cumbersome to read and interpolate these data from a chart or a reference table. Therefore, this app can be very useful for all HVAC personnel including students for obtaining these data with speed and accuracy at given operating temperature and pressure.

Hands-On Equations Level 1 is the fun way to learn algebra for kids age 8 and up. The physical version of the program has been successfully used by more than a million students in the United Sates. 1. Imagine your child CONFIDENTLY solving algebra equations such as 4x + 3 = 3x + 9 after just three lessons, while having fun! Using blue pawns, numbered cubes, and a visual balance model, students quickly discover that algebra can be clear, intuitive, and enjoyable. Instead of memorizing rules, they develop a genuine understanding of the mathematical concepts they are learning. The Hands-On Equations math app transforms algebra into an engaging math learning experience. Along the way, they experience the excitement and satisfaction of solving equations such as 4x + 3 = 3x + 9 in just three lessons, and equations such as 2(2x + 1) = 3x + 10 in just six lessons. These equations are typically not introduced to students until middle school. Yet, your child, age 8 and up, can experience success and joy in solving these algebra equations! These equations are typically not introduced to students until middle school. Yet, your child, age 8 and up, can experience success and joy in solving these algebra equations! ________________________________________ 2. Why children love Hands-On Equations Every lesson builds on previous success through carefully sequenced activities that make abstract algebra visual and easy to understand. Students don't simply learn procedures—they understand why each step works. The elegant instructional design and intuitive app experience make learning algebra both rapid and enjoyable. Students find that this visual learning enables them to solve algebra equations in a few short lessons. Students love the ease with which they can manipulate the blue pawns and numbered cubes, sliding them on and off the balance scale as they solve increasingly challenging equations. The app's elegant simplicity creates a pleasant, intuitive, and highly satisfying learning experience. ________________________________________ 3. What Students Learn in the Hands-On Equations Level 1 App Throughout the six carefully sequenced lessons and one review lesson, students learn: • the meaning of equivalence • algebraic notation • how to check solutions • legal moves with pawns and cubes • equations involving subtraction • equations involving parentheses • confidence that lasts long after the lessons are completed ________________________________________ 4. Proven Success More than one million students have experienced success with the Hands-On Equations Learning System. Originally developed using physical game pieces and classroom instruction, this proven educational approach is now available in an app that makes learning algebra both intuitive and enjoyable. ________________________________________ 5. Who Should Use It? • Gifted children age 6+ • Elementary students ages 8 and above • Middle school students • Struggling high school students • Adults who never really understood algebra ________________________________________ 6. Give Your Child the Confidence to Succeed Whether your child is discovering algebra for the first time or you are finally returning to a subject that once seemed impossible, Hands-On Equations will give your child a memorable, enjoyable, and confidence-building experience with algebra. ________________________________________ 7.
