Relative Humidity and Weight per Cubic Foot Volume of Air
The density and moisture weight can be estimated with the following table - determine the temperature then the known relative humidity to determine the density of water moisture and weight per cubic ft
Humidity Ratio of Air
Humidity ratio W is the ratio of the mass of water vapor to the mass of dry air, Specific humidity γ is the ratio of the mass of water vapor to the total mass of the moist air sample:
Thin Double Convex Lens Optical Equations
Derivation formulas for lens essentially traces an arbitrary ray geometrically and mathematically from an object point through the two surfaces of a thin lens to the corresponding image point.
Refraction for Water at Various Temperatures
Table of index of refraction of liquid water at atmospheric pressure, relative to a vacuum, at several temperatures and wavelengths. It is generated from the formulation in Reference 1, which covers a wide range of temperature, pressure, and wavelength.
Thrown Javelin Flight Dynamics Physics Graphical Simulator
This model simulates the throw of a javelin with no spin and no wind in a vertical plane. This is a simplified situation to be able to analyze the pure dynamics of a javelin throw. The user can change several initial conditions including velocity, angle of the javelin (theta), angle of the velocity vector (phi), angle of attack (phi), and angular velocity (omega).
Roller Coaster Physics Graphical Simulator
This simulation simulates motion along a constrained path, such as what a roller coaster would take (assuming it has safety wheels to keep it on the track in “up-side-down” situations, of course). The simulation offers a chance to explore a number of concepts associated with roller coaster physics, including conservation of energy, reaction forces, motion in a vertical plane and friction.
