Hand calculations for flat plate heat exchanger design using LMTD and E-NTU methods

[MechEngFrank]

I am designing a flat plate heat exchanger for a project and I am not sure where to start with the hand calculations, specifically the LMTD and E-NTU methods, also how to work out the parameters which i will need to complete these methods such as area and number of plates. My deadline is soon, any help is much appreciated.

Perhaps you could begin by giving us a bit more information. ie. the temperatures involved (temperature of the thing being cooled and the initial temperature of the coolant - presumably air), and the specific heat of the coolant.

I would suggest this link will prove to be more usefull to you for getting the desired heat heat exchanger. http://www.gea-phe.com/fileadmin/user_upload/documents/product_datasheets/NA_FP_CH_usa.pdf
