Number tubes required

[amardeep]

Hi,
can anyone suggest me how to calculate the number of tubes required in shell and tube heat exchanger...what are the factors we require to design shell and tube heat exchanger...?

Based on the heat exchange power, fluid properties - specific heat - and available or required temperature change, area for heat exchange can be calculated. Based on that area, tube diameter and length is obtained
