ULTRASONIC TESTING (UT) USEFUL FORMULAE 1. Velocity of Ultrasonic Waves in a medium (V) = f x l OR W here f = Number of cycles per second is called frequency. Measured in ‘Hertz’. Abbreviated as ‘Hz’. One Hertz is equivalent to One cycle per second l = Distance covered in one cycle is wavelength V= Velocity of Ultrasonic wave inside the medium in ‘mm/s’ 2. A coustic Impedance (Z) = V x r W here: Z= Acoustic Impedance r= D ensity V= Velocity 3. R eflection Coefficient

"K-I-S-S" redirects here. For other uses‚ see Kiss (disambiguation). KISS is an acronym for "Keep it simple‚ stupid" as a design principle noted by the U.S. Navy in 1960.[1][2] The KISS principle states that most systems work best if they are kept simple rather than made complex; therefore simplicityshould be a key goal in design and unnecessary complexity should be avoided. The phrase has been associated with aircraft engineer Kelly Johnson (1910–1990).[3] The term "KISS principle" was in popular

1) 0.069 mol MgSO4/ 0.015 mol H2O = 4.6 = 5 Formulae for hydrated MgSO4 = MgSO4 5H2O 2) There are at least two reasons why heating to find percentage of water in hydrated crystals is not recommended for all hydrates. The first reason is that some hydrates have such a strong bond with the water that not all of it will be able to be removed. The second reason is that different hydrates have their own mass. Depending on the mass and type of hydrate‚ some of the molecule may be burned off from heating

Cost‚ Volume‚ and Profit Formulas Heather Jauregui University of Phoenix of Axia College “The Cost-volume-profit (CVP) analysis is the study of the effects of changes in costs and volume on a company’s profits.” (Kimmel‚ P.‚ Weygandt‚ J.‚ & Kieso‚ D. 2003) The analysis is used to maximize efficiency in a business. In order to be effective the CVP analysis has to make several assumptions. These assumptions are that the costs can be fitted into either fixed or variable categories. The
