ChemUtils Pro ChemUtils is a collection of two functions, "moles", and "grams." Both functions have the following syntax: function("chemical formula,n") The moles function returns the number of moles of a given (n) number of grams. The grams function returns the number of grams in a given (n) number of moles. The molecular weight data is not cropped to 3 decimal places, like you see on many periodic tables. The data is provided to as many decimal places as are known. The molecular weight data included in the program is from a reliable source (Kentek Laser Company), but you can use your own molecular weight data, if, for example, you want to have identical numbers to your chemistry classmates, who are all using the table in the textbook, which has idosyncratic molecular weight listings. Because these utilities are FUNCTIONS, you can use them in calculations. For example, you could enter grams("C6H12O6")+grams("H2O,3") on the entry line to get the molecular weight of one mole of glucose and 3 moles of water. Most other utilities like these are programs; they will display the result on the screen, but you can't use it in a calculation just like you can use any other claculator function (e.g. log(),sin(),cos()etc.) This takes the busywork out of all those boring stoichiometry probkems on chemistry tests. No more squinting at the tiny atomic weights on the big periodic table in the front of the class room.

LFGauss1.1 This name stands for “Load Flow using GaussSeidel Method”; it’s written in a TI89 Titanium. The formulas used in it are based on this book: “Power System Analysis by Hadi Saadat”, The program is not written for just giving the final answer, it solves the problem step by step and is specially useful in tests because most of the time you are supposed to solve the problem only for a few steps and write down the procedure, however you can use it for reaching a final answer just by a few changes but when there are programs like POWERWORLD or DIgSILENT I think it won’t be needed. Only those who have solved load flow problem with at least 3 bus and 4 iterations will understand how much useful this program can be however it is still very helpful for smaller networks. There is also a subprogram which calculates the Ybus matrix. The Ybus calculated after running this program can be used in other programs that I have written like Lfnewton or Lffdcpld. By inversing this matrix you calculate Zbus which is helpful especially when you are going to solve a short circuit problem. Required slack bus power, transferred power between buses, power loss on lines, current flowing through the lines and some other parameters of system are calculated too.

Ultimate Motor Helper v2.0 This program is very useful when working with AC induction or DC motors. Ultimate Motor Helper will provide you with the synchronous RPM, breakdown torque, power factor, the value of the starting capacitor required for a capacitor start motor, back EMF, and flux per pole. (Some values only work with specific motors.) All of the information you need for calculations should be on the name plate, except for the number of poles. This number can be determined by a close examination of the stator core. Enjoy! (Note: This program has the distinction of being the first ever to be released on all 12 TI graphing calculator platforms. Yay!)

The program could be used for the whole structure first to determine any external forces, then to find forces in individual members or forces acting at a joint. A maximum of 3 unknowns can be found if forces are applied at more than one point, or 2 if all forces are applied at one point. If there are too many unknowns, you will be prompted to choose a component, which could be a single member, a section, or a joint, involving some of the same unknowns so more equations are generated, perhaps allowing solution. Up to 9 equations in 9 unknowns can be solved. Several examples are included.

Statics (3 dimensional) This program solves three dimensional statics (equilibrium) problems. This update allows the solution of more complex structures, such as trusses, by enabling its application to components of a structure as well as to the structure as a whole. Most commonly, the program would be used for the whole structure first to determine any external forces or couples, then to find forces in members or forces acting at a joint. Each force and the position vector of its point of application, as well as any couples, are entered. Vectors can be entered in rectangular coordinates, or as a given magnitude along a line between two specified points. If there more unknowns than equations, you will be prompted to choose a component, which could be a single member, a section, or a joint, involving some of the same unknowns so more equations are generated, perhaps allowing solution. Solutions are found by means of the TI Simultaneous Equation Solver. Vector magnitudes or vector components can be solved for, but not angles. Angular unknowns can usually be avoided by using components or by specifying direction along the line between two given points. Solutions are saved and copied to the home screen for use in further calculations. Several examples are included.

svpf2ic v1.0 Salam svpf2ic v1.0 Main thing this program can do: • Calculating current of load • Power factor correction (using a capacitor) This program was very useful to me; I hope you enjoy it too. Program description: Most of the time in a power system problem, load is described by the power that dissipates, there are four main situations: 1 S, V and PF are known 2 S and V are known 3 P, V and PF are known 4 Q, V and PF are known Program will ask you for known parameters and then will calculate the current. You won't need to convert line and phase parameter to each other; the program will automatically change your inputs to phase parameters. After the current is calculated you have an option to enter a desired power factor, the program will calculate a capacitor that can be used to reach that PF. For your ease some parameters are stored in one letter variables: • Z = phase impedance of load (used in impedance model) • X = phase reactance of capacitor • V = phase voltage • S = phase apparent power • Q = phase reactive power • P = phase active power • I = phase current • F = frequency Notice: • There is always a 30 degree difference between phase and line parameters.
