SPEED: Engineering Scratchpad

SPEED, which stands for '[S]cratch [P]aper for [E]fficient [E]ngineering [D]eduction' is a powerful visual notepad. It is an equation-based line-by-line interpreter where equations and results are displayed simultaneously. Variable names can be utilized and re-used. Array variable is allowed which enables iterative calculation. It is also equipped with CoolProp fluid properties and IAPWS-IF97 water property function. Last, it works on plain ASCII text files which can be read and shared easily with others. Great for on-the-fly, simple to complex engineering calculations. Power of desktop class software on palm of your hand. Right companion for solving elementary to practical level engineering problems. Following features are currently supported. - Simple to complex arithmetic calculations - Simultaneous display of equations and results - Variable assignment based connected calculations - Array variable supported - 5 level depth repetition loop - Text output (echo) manipulation - 1D, 2D linear interpolation - CoolProp fluid properties - IAPWS-IF97 light water property calculation - Non-linear equation solver (1 variable) - Linear equation solver (A*x=b) - Extensive unit conversion factors - Extensive statistical functions - 1D, 2D, 3D plotting - Other useful functions (pressure drop, heat transfer)
