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

How To Prepare Infant Formula Infant formula is an alternative to breast milk. It comes in three forms: Powder. Concentrated liquid. Ready-to-eat. BEFORE PREPARING FORMULA: Check the formula’s expiration date. Do not use formula that is expired. Check the formula’s label to see if you will need to add water to the formula. If you do need to add water and if you are going to use well water or bottled water‚ boil the water for at least 1 minute. Then let it cool. Make

HCC130 - Fundamentals in Health Care Delivery Breastfeeding Vs. Formula-feeding One of the first decisions that expectant parents need to make is to decide whether they want to breastfeed their child or bottle-feed the little one. Everyone has their opinions as to which method is better for their newborn and there are numerous studies these days concerning the pros and cons for each method. Although breast milk is the most nutritional choice for newborn infants‚ that is not always the best choice
