Analysis of position and check Grashof of mechanisms (4 barras).
HVAC duct sizing and analysis. Accommodates round and rectangular duct sizes and variations in roughness, air density, and dynamic viscosity. Uses DARCY function. Works on all 48 and 49 models.
Graphically represents the state of the stresses or strains, using Mohr's Circle. The program performs the necessary calculations to find the principal directions and principal values of a symmetric tensor in XYZ Cartesian coordinates, and the maximum values for the shear stress or shear strain. In-plane case, the stress or strain that act on plane defined by angle θxy (counterclockwise positive), the program additionally shows the normal stresses or strains, shear stresses or strains, and the angle necessary for the stresses or strains to be maximum. In a three-dimensional case, the stress or strain act on plane defined by normal vector VNP (three-dimensional vector), the program additionally shows the normal and shear stress or strain vectors.
Tables for Fanno, Isentropic and Rayleight flows. Just put the value on stack, run the program, enter what sort of value it is (M, P/Po, etc), and you can change K value. Made in User RPL.
Simple program to analyze the kinetic of a rigid body in 3D-space. You can get the maximum, the minimum and the median inertia momentum. Also, you can obtain the angular momentum and solve the Euler's Equation.
Effective Number of Bits Calculator (ENOB) aids in the design and analysis of data converter application circuits. It calculates ENOB, SINAD, resolution, signal bandwidth, oversample rates, DNL, clock jitter, analog noise, and THD.
Contains all the equations used to analyze a load through combined forces, for use with a mechanical design course.
Performs calculations on structures, including porticos and celosias.
External ballistics program. This is a projectile motion problem with air resistance included, and it is a nasty bugger (mathematically speaking).

The premier structural analysis software for both the 48G and 49/50 series calculators. Its ease of use, flexibility, power and capabilities combined in one package are not seen in any other program available, either commercially or as freeware. FEM48/49 solves frames, trusses and continuous beams. Includes wizards for geometry, sections and loads. Links to SED48/49 database. An extensive manual is included. Completely written in SysRPL. SR6 has been adapted for the larger screen of the 49g+ and 50g.
Solves Heisler diagrams analytically for transitory heat transfer.
Calculates the maximum momentum and normal forces that can support a reinforced concrete section, and then, draws the domain.
This library evaluates the solar irradiation on a bent plane, looking for a bettering of both the dimensioning and analysis of the solar water heating systems.
Calculates moments of inertia, center of gravity and area of flat sections formed by rectangles, right triangles, circles and quarter-circles. Also supports coordinate-oriented input and language setup.
Calculates the compressibility factor with the tables of Lee and Kesler for Thermodynamics). First version for the HP 49G.
Gives information on liaisons (connections) including a description, its degrees of freedom, its torque, a diagram, and more.
This is a beta release of the upcoming Mohr program for the 49. Currently it will calculate principal stresses, a well as those at a prescribed plane angle. It is also (I believe) the first program for the 49G to implement Step by Step solutions. Version 1.0 will include graphical construction of Mohr's circle and element diagrams.
Provides both numerical and graphical solutions to Mohr's stress circle.
Simple program to analyze the particle movement either in Cylindrical Coordinates or Spherical Coordinates.
A simple and totally functional User-RPL program to convert parameters of two-terminal-pair networks. This program can convert between parameters of admittance [g], impedance [r], transmition [T] and hybrids [m] y [h]. Also, it can help you showing relationships that have to be met for a network to be symmetric or reciprocal.
Psychro is a program for doing psychrometric calculations. Both SI and English units are supported, in a manner consistent with the Equation Library.
R134a refrigerant tables program, useful for thermodynamics, refrigeration and air conditioning courses.
Program to perform calculations with the equations of special relativity.
Contains all the equations used to analyze a spring, for use with a mechanical design course.
The program determines for a single-span girder having restraints with reference to rotations at both ends the support moments, reaction forces and maximum field moment. The degrees of restraints may be in the range of 0 % to 100 %. Accepted are up to 25 trapezoidal knife-edged and individual loads. Now the combination of attached end-/cantilever moments and elastic restraint at the same support is provided. Tested for both the 49g+ and 50g.
This program determines the equivalent spring constants (vertical and rotational spring) of a one-field beam at any point of the length given its rigidity and the conditions of support at both ends. Tested on the HP 49g+ and 50g.
Statistical Process Control Calculator (SPCC) aids in the prediction and analysis of process yield. It calculates defects per million, yield, process shift, standard deviation, mean, and the lower and upper specification limits.
Air properties program.
Thermal Noise Calculator (TNC) aids in the analysis of thermal noise found in resistors and other noise sources. It calculates noise voltage (µVpp and µVrms), noise density, Johnson resistance, temperature, upper and lower frequency limits, and corner frequency.
This library contains five state equations (virial, van der Waals, Redlich-Kwong, Redlich-Kwong-Soave, Peng-Robinson), six equations for activity coefficients (Symmetric, Margules, Van Laar, UNIQUAC, UNIFAC), and four programs for calculation of bubble temperature and pressure, and dew temperature and pressure. Also includes the Antoine equation for 3 and 5 parameters.
Improved (graphic interface) version of the program "steam" by William David Eisenhauer and Allen Arnold, Portland State University. It doesn't change any calculation property, it only makes it easier to use.

Calculates the density of water, given the temperature in Celsius, pressure in Pascals, and whether the water is pure or from the tap. Based on Tanaka's work. As a function of pressure (or altitude and local temperature), it is also possible to get the local boiling temperature of water according to equations of Goff-Gratch (1984) and Arden Buck (1996).
