The next step is to decide which type of exchanger to be used?The industrial heat exchanger are varies depending upon 1. Transfer process.2. Number of fluids3. Compactness.4. Constriction.5. Flow arrangement.6. Type of heat transfer.See attached figure for more details.
<p>The first step dorm designing a heat exchanger is to understand where it will be used for.</p><p>Application is most important criteria and mostly its input from client.</p><p>Application demands understanding of functionaries expected, duty needed, properties of both side fluids, system information e.g presuredrop expected, cleaning method of the equipment, hazard category, local laws pertaining to […]
Lets Start with Diffrent Loading CalculationStep : 11. Heat Loss to Atmosphere : Surface Area m² X Delta (Tavg – Troom)ºC x 0.32 = Q1 kcal/ hr2. Cooling Load : Volume of liquid (lits) x Delta (Tstart-Tend)ºC/Time (hr) = Q2 kcal/hr3. Heat evolved during Chemical process/ Fermentation : Q3 kcal/hr Total Heat to be Removed […]
Ok, So you want to design cooling for a vessel.. how to? Step : 1 : What you should know, and what you should askWhat you should know a) You should know what type of Vessel Construction your are offering b) You should know what Jacket for cooling you have c) You should know your […]
Just, I got this info & sharing with youDensity of MilkWhole milk : ρ = 1035.0 − 0.358 T + 0.0049 T^2 − 0.00010 T^3Skim milk : ρ = 1036.6 − 0.146 T + 0.0023 T^2 − 0.00016 T^3Buffalo milk : ρ = 923.84 − 0.44 TCows’s milk : ρ = 923.51 − 0.43 T […]
Dear All, Recently i was working on designing tanks with cooling jacket.In brewery in particular, there is lots of need of cooling of tank, to take care of heating load generated out of fermentation, surface losses & to get temperature profile. and as a motive to open this blog, is to share what i learn, […]
Whats is Earth quake factor? and how they affect the calculation? Their are numerous papers on this, and they are equally qualified to tell you what is earthquake factor all about… but what mater to me is.. how do they do it! As far as India is concern..The earthquake of 26 January 2001 in Gujarat […]
All designers are accustomed to evaluating moments due to eccentric and wind loads, but there are a few who may not be familiar with the method used for estimating moments due to earthquake. Therefore, the following brief outline is presented because this method is recommended as a design procedure for vessels where dynamic considerations are […]
It is customary for most vessel designers to establish the minimum vessel shell and trend thickness according to the pressure temperature conditions and then calculate the thickness required at the bottom head seam due to bending moments imposed by wind or earthquake forces. Stresses in the longitudinal direction are involved nod the following notation maybe […]
External pressure can be due to internal negative Pressure, or external loading like wind, earthquake etc. or live load, snow load etc. One can design Pressure vessel for either sever combination of various load or for most possible occurrence of load combination. Load combinations are given in respective ‘Building Code’ like API, UBC, IS etc. […]
