Shell tube HX eNTU calc ho

[@nickram5061]

Great video. Sir, do you have a data for number of tubes by pass?

[@AhmedTaha-ij8xj]

how did you get the heat capacity of cold fluid if the mass flow rate is not there??

[@ayeshaaftab6227]

How did u calculate nusslets number please explainnn

[@franklincoloma2185]

How did you get Q?

[@alialame2011]

Hi, Mass flow rate of cold fluid is not given, how did you get the heat capacity?

[@reedpetersen]

Lots of tables have heat capacities tabulated.

[@AhmedTaha-ij8xj]

@@reedpetersen have you any table which has heat capacity in it ?? cuz i couldn't find one

[@reedpetersen]

@@AhmedTaha-ij8xj just google “heat capacity of oil” or whatever you want to know the capacity of.

The reynolds number was calcualted incorrectly. The density of the fluid was completely neglected in the caclulation

[@sanaaade7698]

yes .it is wrong it will be laminar flow

[@janAlekantuwa]

Incorrect. v = 4m'/(rho * pi * D^2 * number of tubes).
This leads to Re = 4m'/(mu * pi * D * number of tubes). He factored in the number of tubes into his value for m', meaning that he number of tubes term in the denominator can be disregarded, leading to the formula he wrote down. He did things right

[@reedpetersen]

Density of water in SI units is 1, so ya he's fine.

[@reedpetersen]

What textbook do you use?
