Online calculator for engineering students11/23/2023 ![]() Thermal properties of water at different temperatures like density, freezing temperature, boiling temperature, latent heat of melting, latent heat of evaporation, critical temperature and more. Psychrometric chart for air at barometric pressure 29.921 inches of Mercury and temperature ranging 20 oF to 120 oF.įree online UTM to Latitude and Longitude coordinates converter. ![]() Hot Air Balloons - Calculate Lifting WeightsĬalculate hot air ballons lifting forces.Īir - Psychrometric Chart for Standard Atmospheric Conditions - Imperial Units Linear temperature expansion coefficients for common materials like aluminum, copper, glass, iron and many more. Thermal Expansion - Linear Expansion Coefficients Water Supply Systems - Online Design Applicationįree online tool for designing water supply systems in buildings. Thermal properties of air at different temperatures - density, viscosity, critical temperature and pressure, triple point, enthalpi and entropi, thermal conductivity and diffusivity and more. That one is not yet available, but almost - Once it is available and I test it, I may change the owner of the crown for now.Steel Pipes - Calculate Thermal Expansion LoopsĬalculating and sizing steel pipe thermal expansion loops. See I don't want a calculator that resembles what I will do with a computer.if that is the case, the HP PRIME shall be your best bet or the alikes from CASIO or TI.It will be cheaper and it will be more powerful.ĭo your research as it is part of the fun, but before finishing - take a look on the link below: A couple of reasons besides the german link posted below:ġ - You have a clone that works exactly the same in your mobile phone.Ģ - Portability - My HP15C and the DM-42 are, surprisingly almost the same size!ģ - You have a reasonably good way to customize for you mainly used functions (Custom Men - which picks the best from your catalog of functions).Ĥ - Not rechargeable - and it takes long to discharge - if you need something superfast and superfancy - you will be better served on a computer.ĥ - Easy to program - really, really easy.ħ - You can save your programs on a computer.Ĩ - You have what they call states - so you can have two or three setups (Let's say - financial, Physics, Electronics). I would go for the DM42 today (I have one) or wait for the WP43S that I think shall come at any time. If you're in love with rpn, dm42 is pricy but a very precise tool base on free42 with a full metal case. HP35s is quite different because no mathprint, but have a nice solver and a nice scripting, programming interface and a rpn input entry. Solver, basic complex, table, mathprint, dec to hex to bin conversion, constants. If you are looking for a everyday tool, I find scientific quite enough.Ĭasio fx-991ex anf TI 30 x pro mathprint are great tool. Old calc like TI89, HP50g a great, powerfull, have a ton of programs and even books about real life engineering jobs. Numworks is great as adult tool if you're interested in dev. I tend to find TI84, Casio cg50 not so interesting with this perspective. Full metal, keys, sreen are a few steps ahead of TI or Casio. Step by step prog, reading pdf.Īs a high end, the HP prime is a better choice with a top nocth quality. But I can't stop thinking of it as an educational tool. This comment may be not the most informative (as I don't know that much about the newer calcs - and I don't know nothing about the Casio calcs too, but I heard they are pretty nice) but I tried haha If you want something more modern but you love RPN and want to try some nice wifi and touchscreen capabilities try the HP Prime. If you want something more modern and heavy with loads of keys try a TI Nspire CX Cas II. If you like Python get a Numworks (this one also has the mod of installing a Raspberry Pi and turn it into a full linux computer). If you love RPN and want a classic HP Calc with a nice keyboard get a HP 48GX. If you love RPN and wants a newer calculator with a more updated library of user apps and some exclusive advanced functions get a HP-50G. If you want a smaller V200 that is allowed in every exam but without the keyboard get a TI-89. However it may not be allowed in exams and may not have the newest of apps/programs and features - as a USB port - it has a I/O to USB cable instead - that is not that fast in transfering your programs -, touchscreen, a color display or loads of memory - only 2.7 MB - neither expansion capabilities). Voyage 200 (it's cheap, has a qwerty keyboard, the biggest screen a calculator has, support for Basic, ASM and C, one of the biggest libraries of user-made programs - as it runs TI-89 and TI-92 programs as well - it's cool looking, robust and works on double A batteries that last a long time.
