Welcome To The Blow Out Page

The following spread sheets have been collected over a 31 year period. These 300 plus excel programs have been created by professional people that have been in the patch for a long time, some I have had the privilege to work with. They are presented to you free of charge. This web-site is dedicated to all oil field workers, past and present. May you go home the same way you came. If any of these are patented or have rights please contact and they will be removed immediately.

Gas Molecules Simulation

Sorry, you need a Java-enabled browser to see the simulation.
This java applet is a simulation that demonstrates the kinetic theory of gases. The color of each molecule indicates the amount of kinetic energy it has.

Press "Reset" to reset the positions and velocities of the molecules to random values. Pressing "Reset to Equal" will cause the velocities to all be the same, although they won't stay that way for long."Reset to Extreme" will reset half the molecules to a single large velocity and the other half to a small velocity;again, they won't stay that way for more than a fraction of a second. "Set Wall Temp" will set the temperature of the walls to be the same as that of the heater.

The volume slider controls the volume of the container. The Heater Temperature slider controls the heater at the bottom of the screen; if the temperature is high, the heater is more likely to give a large kinetic energy boost to molecules that hit it. If the temperature is low, the heater becomes a refrigerator; it removes kinetic energy from the system. The gravity slider controls gravity.

At the bottom of the screen is a velocity histogram showing the distribution of velocities of the molecules. Again, color is used to indicate velocity; velocities increase as you go to the right on the graph. The height of the velocity bars shows the number of molecules that have that velocity. The scale of the graph changes constantly so watch the colors to orient yourself.

One-dimensional one-atom gas

Below is a very simple model of a gas. Here, a single atom bounces elastically in a one-dimensional cavity. It will continue to bounce at the same speed forever if the piston does not move. If we start the piston compressing, the atom gains speed when it bounces off the piston. (speed after collision) = (speed before collision)+2*(piston speed). That alone is enough to explain why a gas heats when we compress it and cools as we allow it to expand.

This is a Java 1.1 applet demonstrating a one-dimensional piston.

Convert Kelvin to Fahrenheit and Celsius

Keep in mind that absolute zero is the lowest possible temperature so if you try to enter a valus less than 0 Kelvin, you get an impossible answer.
