Dwight, dead on! Man, you guys are brilliant when it comes to sciences. This forum covers pretty much the entire array of PhD to field-based experienced gurus. This is where historical data from NOAA comes in handy, as well as some Almanac info, since Texas is a bit behind on their information updates. Once the info get tabulated, you then utilize 4 equations to calculate for the speed of transevaporation. Unfortunately, it has to be done by hand. This is where calculus comes in handy.
I am sure Maple could handle it. I know a professor that used Maple to solve five equations, five unknowns for his 8 yr son's pine wood derby car to make sure the weight balance was correct.
I am kinda partial to Mathcad myself. They both are really cool programs.
PTC recently released a free version of Mathcad. A number of advanced features are disabled, but I doubt the vast majority of people would use them.
My last upgrade was in 2008, and none of the hundreds of apps I have written over the past 23 years will import into the free version. They need to be converted with the latest full version, which I am not going to get.
If the default windows scientific calculator is over your head, then you defiantly don't even want to be messing around with the free version, unless you like math
