The 50g is a very powerful beast, bridging the gap between calculators and computers, although it is still technically a calculator. One simply has to look at the range of software available for it and the 49g+.
Is it suitable for students in an exam situation? In my humble opinion, probably...
I can only concurr with jaschandler. The older HP calculators, from the HP35 onwards, had a stack (x, y, z and t) and the machines only displayed the 'x' and the user had to remember what was in the 'y, z and t'. This made life very confusing. Did pressing 'ClX' just clear the x display to zero...
Some help please.
I'm writing a units application and I want to convert cubic meters /day into millions of cubic meters a gear. The first one is easy '1_m^3/d' but when I try '1_Mm^3/yr' it gets interpreted as 'million meters cubed per year.
I've tried putting brackets i.e. '1_M(m^3)/yr' and...
Taking the now infamous equation, '-2^4', the minus sign at the beginning is monadic and must mean that the numeral 2 is negative. The HP calculators have, for as long as I can remember (35 years or more), used the +/- key to negate a number. The - key is an operator and is diadic (that is it...
Well as I think I was trying to say my backgrond is in gas but I think the basic thermdynamic principles can apply to metallurgy as well. Take for example 2,2 dimethyl propane. The molecule is basiclly a tetrahedron and it packs more efficiently than methyl butane or normal pentane itself; this...
Have you never heard of the marbles effect? This concerns itself with the most efficient packing efficiencies and the lowest energy states associated with them. I'm a Chem Eng and this comes into that in a major way in gas behaviour.
Basically most things on an atomic scale "want" (to...
I've been a practising Chem Eng for 30 odd years moving from the food industry (3 months) to the petrochem industry (7 years) and ending up in the offshore gas industry in the UK (how did I get there?).
Apart from the food industy, I was very happy and was always challenged by the work I did...
I don't know wheter this helps or not, but when I started off as a practising Chenical Engineer I worked in the juice concentration industry and we used steam ejectors a lot. I seem to remember (it was 30 years ago) that a UK manufacturer of ejectors called Hicks and Higgs produced a good manual...
I could go on for hours about combustion and will write a fuller reply. Essentially Beychock is correct, you must remember the stoicheometry.
One mole of methane requires two moles of oxygen to produce one mole of carbon dioxide and two moles of water so equating moles to volumes (which is not...
HP50g
I've been using HP's for the last zillion years (or at least since the first HP 35). RPN, when I first met it was confusing but after 10 minutes or so playing with it, it made complete sense to me and I found it easy to use. I have been using HP calculators ever since. Despite my moniker...
