All Calculators Require a JAVA Enabled Browser. More Information
Note:

Many of the links first open an equations web page. Look for the the "Calculators" link to open the actual calculator application.

Not all web page actually open to a calculator at this time, however there will be the associated calculator in the near future.

Bloom Filter Calculator False positive matches are possible, but false negatives are not – in other words, a query returns either "possibly in set" or "definitely not in set". Elements can be added to the set, but not removed (though this can be addressed with the counting Bloom filter variant); the more items added, the larger the probability of false positives.

Sphericity of a Sphere Formulas and Calculator Sphericity is, naturally, a measure of how spherical an object is. Defined by Wadell in 1932, the sphericity ψ of a particle is the ratio of the surface area of a sphere with the same volume as the given spherical particle to the surface area of the particle.

Poiseuille's Law Formula and Calculator The relationship between pressure and continuous laminar flow of fluid in a rigid tube is described by Poiseuille's law, which states that the flow rate of a fluid, Q, is directly proportional to the pressure difference, along the length of the tube and the fourth power of the radius of the tube, and inversely proportional to the tube length, and fluid viscosity.

Capital Recovery Factors Formula and Calculator The future equal payments to repay a present value of money is determined by the capital recovery factor, which is the reciprocal of the present worth factor for a series of equal payments.






Life Cycle Costs Formula and Calculator A representation in present dollars of the cost of an investment over its lifetime is useful for evaluating mutually exclusive alternatives that have the same anticipated lifetime.

Meeting Cost Calculator  How does the estimate work? We calculate the average hourly cost of each attendee and multiply it by the number of attendees and the duration of the meeting. You can help make the estimate more accurate by..
