Unit 07 1Q) Give a comparison of parallel flow and counter flow heat exchangers. Why are counter flow heat exchangers mosly used? 2Q) Determine the overall heat transfer coefficient based on the outer area of a 3.81cm OD and 3.175cm ID brass tube (k=103.6w/mk) if the heat transfer coefficient for flow inside and outside the tube are 2270 and 2840w/m2k respectively and the unit fouling resistances at inside and outside are Rfi=Rfo=0.0088m2k/w 3Q) Derive an expression for logarithmic mean temp difference

Tá ceist na dtáillí uisce idir dhá cheann na meá Nuair a tháinig ceist na dtáillí uisce go béal an phobail‚ bhí mearbhall ann de bharr an fáth a bhí air muintir na hÉireann íoc do riachtanas bunúsach cosúil le huisce. Bíonn sé ag cur báistí 225 lá sa bhliain in Éirinn‚ agus d’aithneodh dall gan súil nach bhfuil ganntanas uisce againn. De réir an rialtais‚ an fáth go bhfuil táillí uisce le teacht isteach ná de bharr an t-uisce do-ólta atá in áiteanna sa tír‚ chomh maith le hinfreastruchtúr

Planning Aim In this experiment I will be testing the effect of temperature on the plasma membrane of a beetroot. I will do this by measuring the percentage light transmission using a spectrophotometer. Once I have obtained my results‚ I will justify them using scientific knowledge explaining what I have observed whilst carrying out the experiment. Factors to be controlled "« The pH concentration "« Regular use of distilled water "« Ensuring that the surface area of each piece of beetroot is

Effects of Tonicity on Cell Membrane Abstract The purpose of this experiment was to determine the effects of tonicity on a cell membrane using red blood cells‚ potato strips and three unknown solutions (A‚ B‚ C). First three slides were prepared containing RBC’s and unknown solutions A‚ B and C. A control slide was prepared only using RBC’s. After observing each slide under the microscope it was determined that unknown solution A was hypertonic because the RBC appeared to have shrunk. The
