Thank you very much for such a kind response, i have studied these topics ... these are quite interesting ... i am studying single phase "pressurized water reactor" ... my main focus is on the pressure drop across fuel rods and pressure drop in steam generator , i am neglecting all minor losses...

oh ok ! and its ok thank you for your kind support best regards!

I am from Pakistan

again not working time out error is displayed on screen

third link is not working ...

thank you! can you provide me the link from where i can get the MIT exam paper to solve .. for these topics

Hello! I am studying the mentioned topic I am confused in calculating the average value of friction factor in sub channels ... please help ?? thank you in advance

Hello! I am studying the mentioned topic I am confused in calculating the average value of friction factor in sub channels ... please help ?? thank you in advance

thank you for reply sir, yes i got it, it is the total flow rate through duct .

i assumed it is parabolic as laminar has parabolic profile ..flow was laminar

Vz\Vm=2(1-r^2/R^2) this is the relation Q=A*v but how to initiate ? should i specified the boundary condition then integerate or can do some numerical analysis to evaluate integeral or find out the mean value of velocity then proceed ...

Respectable @Astronuc thank you for the kind response sir, please if you can provide help regarding pressure drop calculation mentioned in kazmi book ? question is what is the main difference in calculating the pressure drop across one fuel rod and entire core . chap #9 single phased fluid...

Thank you for kind response sir , it was a question in exam ... like r=0,1,2,3,4,5 v=2,1.92,1.68,1.28,0.72,0 numerical values may be some digits different but i need to understand a problem . now if diameter is 10cm then calculate the flow rate ?

hello! i was provided by the radii from 0 to 5 cm and a parabolic profile is also given .. in numeric form i was asked to calculate the flow rate how to understand it to solve further kindly help ...

thank you very much i have taken a course on fluid mechanics but i think i was unable to understand it well ... as our class consists of mechanical engg as well as scientists so the very basic knowledge was not provided so i was unable to handle problems in paper ... i need to understand the...
