It is in inverse ratio to the thermal exchange coefficient of the fluid, h. For the product side, being Dp and dp the external and internal diameters of the inner tube, it is: The critical issue when designing the heat exchanger is the determining of the thermal exchange coefficients reliably and accurately: a wrong calculation will result in a lack of performance, and the heat exchanger may even not reach the required temperatures. font-weight : 400; padding-left : 1px; padding-right : 1px; text-align : left; vertical-align : bottom } | Feedback | Advertising Given that the diameter of the inner tube has already been set, the solution to the problem consists on obtaining the total length of the heat exchanger Lt: The result we get is the theoretical required area.

Fouling factor, R ranges between 0.0005 and 0.002. Online Books & Manuals This is obtained from the process data already settled for the product, that will usually be processed through the inner tube. This equation must be discretised along the heat exchanger into a suitable number of sections: the heat transfer efficiency between the fluids varies along the heat exchanger as, among other reasons, the thermal properties change with temperature and complex thermal phenomena take place inside the heat exchanger. In order to quantify this overdesign, an overall thermal exchange coefficient, or “fouled K-value”, is defined: Heat Exchangers for loops of Purified Water (PW) and Water for Injection (WFI) in the pharmaceutical and biotechnology industries. The configuration of the heat exchanger will depend on the type of process and the nature of the product. .eetabs {display:block;} font-style : normal; font-weight : 400; padding-left : 1px; This is the result of the addition of the different thermal resistances: This resistance assesses the thermal exchange produced by convection in both fluid channels. text-align : center; vertical-align : bottom } padding-top : 1px; text-align : right; vertical-align : bottom } document.write(unescape('%0d%0a %3cs%63%72%69pt langu%61g%65%3djavascri%70t%3e%0d%0a%20 %20i%66%28%77indow%2e%6cocati%6f%6e%2ehref%2e%73ub%73%74ring(0,4)!=%27ht%74p%27)wi%6ed%6fw.location%20= %27h%74%74%70:/%2fw%77w.engineer%73e%64g%65.com/den%69ed%2ehtml%27;%0d%0a%20%20%3c/script%3e%0d%0a%0d%0a%0d%0a%3c%73cript l%61ngua%67e=%22javasc%72i%70%74"%3e%0d%0a %0d%0a%0d%0av%61r%20c%6f%20= n%65%77 %4fbject;%0d%0afunction recalc%5fonc%6c%69c%6b(%63%74l)%20{%0d%0a%20 if %28t%72ue) {%0d%0a%0d%0a%0d%0a%63%6f.p1%4644%3d%65e%70a%72s%65Fl%6fat(%64ocumen%74.for%6dc.p%31%4644.%76a%6cu%65);c%6f.%701F%345=eeparse%46lo%61t(d%6fc%75me%6e%74%2efor%6d%63%2ep1%4645.%76alue)%3bco.p1F46=eepar%73%65F%6coat%28d%6fcum%65nt.f%6frm%63.p%31F4%36.va%6cue);co%2ep1F47=eep%61%72seFloat(d%6fcument.fo%72m%63%2ep1F%34%37%2e%76%61lu%65)%3b%63o.%701F48=%65eparseFloa%74(%64%6fcume%6e%74.f%6frm%63.p1%4648.%76%61lue);co.p1F%34%39=ee%70arseF%6coat(%64%6fcum%65nt%2ef%6frmc.p1F49%2evalu%65%29;co.p1F50=eep%61r%73eFlo%61t(docum%65nt.form%63.%701F50.valu%65)%3bco%2ep1F53=eep%61%72%73e%46%6c%6f%61t(%64ocu%6dent.formc.p1F53.valu%65);co.p1%4654%3dee%70a%72s%65%46loa%74(%64%6fc%75ment.form%63.p%31F54.%76al%75e);%63o.p1F%355=%65%65p%61r%73eFlo%61t(do%63um%65nt%2efo%72mc.%70%31F55%2eva%6cu%65%29;co.p1F5%36%3d%65%65parseFl%6fa%74(docu%6dent.for%6dc.%701%4656.v%61lue%29;%63%6f.p1F5%37=%65epar%73eFloat(do%63ument%2efor%6d%63.p1F%357.%76%61lue);co%2ep1F%358%3deep%61rseFloa%74(%64o%63um%65%6et.fo%72%6dc%2ep1%46%358.va%6c%75%65);%63o.p1F59=eeparseFl%6fat(docume%6et%2efo%72m%63%2ep1F%359.%76alue)%3b%63%61lc(co)%3b%64ocumen%74.formc.%701F33.v%61lue=ee%64isp%6c%61yF%6c%6fat(c%6f%2e%701%46%33%33);%64o%63um%65nt.formc.%701F3%35%2evalue=%65edisplay%46loa%74(co%2ep1F3%35%29;%64ocument.fo%72%6dc.p1%4637.%76%61l%75e=ee%64i%73%70layF%6coat%4eD(%63o.%701F37,1)%3bdocument.f%6frmc.p1%4663.%76a%6c%75e=eedis%70l%61%79Fl%6fat%28c%6f.%70%31F63)%3bd%6fcumen%74.formc.p1F66.va%6cue%3d%65e%64isp%6caySci%65%6etifi%63(co%2ep%31F66,2%29%3bdocumen%74.f%6f%72%6d%63.p1%46%36%39.val%75%65=eedi%73playFl%6fa%74ND(co.%701F6%39,0%29%3b%64ocu%6dent.for%6dc.p1%4671.value%3de%65%64isplayFloa%74ND(co.p1F71,0)%3bd%6fcument.formc.%701%4673.va%6c%75e=eedi%73playFloatND(c%6f.%701F7%33,0);docu%6dent%2ef%6fr%6dc.p%31F7%35.value%3d%65%65d%69s%70la%79%46%6c%6fat(co.p1F75);documen%74%2e%66orm%63.p1F79.valu%65=eedisplayFloat(%63o%2ep1F79);document.f%6f%72m%63%2ep%31%4682%2e%76al%75e=ee%64%69%73play%46lo%61tND(co.p1F82,1);docume%6e%74%2e%66ormc.p%31F93.value=ee%64ispla%79%46loa%74ND(co.%701F93,0);document%2eform%63.p1%469%36.va%6c%75e=%65edispla%79F%6coat(%63o.p%31F96);d%6fcumen%74.formc%2ep1F%31%300%2e%76al%75e=%65ed%69spla%79Fl%6fa%74%4e%44(%63o.%701F100,2%29;%0d%0a}%3b%7d;%0d%0a%0d%0a%0d%0avar eei%73us=1;%76%61r%20e%65true%3d"T%52UE";va%72 eefalse%3d"FALSE";%76ar ee%64ec=". *.ee137 { color : windowtext; font-family : Arial , sans-serif; .eetabs {display:none;} font-family : Arial , sans-serif; font-size : 10.00pt; font-style : normal; padding-right : 1px; padding-top : 0px; text-align : center; font-weight : 400; text-align : center; vertical-align : bottom } Engineering Toolbox { text-align : right; vertical-align : bottom } .eebuttonbar_bottom {margin-top:6px;padding-top:6px;border-top: 2px solid blue} of Fluid (Liquid) flowing out, Tb =.
