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

Professor Tolentino Maria Oyervide EXPERIMENT #4 IONIC AND COVALENT COMPOUNDS Abstract: This experiment was divided in four steps to find the electrical conductivity of covalent and ionic solutions. There were four unknown solutes A‚ B and C. Each had a specific weight and was dissolved in a certain amount of solute to form either the covalent or ionic solution. Covalent compounds are made up of molecules which are electrically neutral. Ionic compounds are composed of ions‚ which are positively

Chemistry December 14‚ 2010 Conductivity of Ionic solutions Introduction This lab report is about the conductivity of ionic solutions. In class we have been discussing wether all ionic solutions conduct equally well. If an solvent solution conducts electricity‚ then it must contain ions. So measuring the conductance of solutions can tell you whether the solutes in the solution are dissociated into ions. (Conductivity) Any type of solution‚ even ionic solutions‚ provide resistance to the flow of

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
