    Calculating Condenser Backpressure

    1.- heat load in each zone? How accurate is your measurement of this? I calculated it with the CW delta T. The Flow was taken with a radioactive trace and the density and specific heat was taken according to inlet temperatures. 2.- Are your inlet and outlet water temps actual measurements also...

    Calculating Condenser Backpressure

    EdStainless Could you review my calculation? (see attached) I did the following calculations: 1.- Calculate TR (TR=(T3-T1)/2) and then i got T2 2.- Calculate Q1 and Q2 (Q=density*Cp*(To-T1)) 3.- I make the assumption that Q=Qmax...so Q=(Cp*m (min)*(T hot - T cold) 4.- I got Ts and compare it...

    Calculating Condenser Backpressure

    I've made some calculations according to the plant signals data (see attached). But for the CF how should i consider it? on invidual boxes or should i take an average? For example, on the sheet named "5 Oct 2001" I have individual CF of: B-CF%: 98.2440293% A-CF%: 93.4345511% But if I...

    Calculating Condenser Backpressure

    Attached you can find some data from the last year. On the top of the page there is information about the dates and description (also in english....sorry for the last translation). I've marked on red the information that might be useful. There are some signals that were out of service....those...

    Calculating Condenser Backpressure

    Hello all, I am calculating a condenser clean factor, our condenser is a surface multipressure condenser. I have acces to data of the follwing instrumentation: CW inlet temp (t1) CW outlet temp (t2) CW flow (wg) Steam temperature (ts) According to the HEI i have calculated the cleanfactor of...

    Calculation of condenser performance

    Hi everyone, Does anyone has an example of a calculation of condenser performance? I am following the HEI 10th edition... I've calculated the design conditions according to the datasheet of the condenser and the thermalkit... But for real conditions...what should i use? thanks.

    Material compatibility

    I am interested on knowing what could happen if I place a valve that has on its material composition A216 GR WCB cast steel on a A312 TP304 Stainless steel...is it convenient to do this? Does it exist a table of compatibility of materiales? Thank you in advance.

    How can I calculate the volume inside a pump case?

    The pump is installed on plant, so it is difficult to access to it, do you have idea if with the pumped fluid information, speed, curve and that stuff, could i get that information?

    How can I calculate the volume inside a pump case?

    I have to determine the heat increase on a pump that its discharge valve is closed, so it will be operating at shutoff pressure for 10 seconds. I have the design information of this pump, the curve of the pump, with its outline drawing and data sheet. is it posible to calculate the case water...
