Heat Ex-changer Calculations

    Hi all, I am trying to work out a few calculations on a plate heat ex-changer. Any help would be greatly appreciated.

    On the primary side there is 90 degrees Celsius going in and 70 degrees Celsius going out at 30.1 m3/h

    The secondary side I have 65 degrees going in at 17.8 m3/hr.

    The question is what temperature will I have coming out of the secondary side and kW will have been exchanged?

    What is the correct formula to use for this? Is the size of the Heat ex-changer needed?

    Ports are DN 80

    Need this to find out a figure that is missing in a schematic of a CHP system.

    Thanks!

    Well it's frowned upon to do homework for people..

    What equations are you familiar with; tell us your guess at a method and maybe we can inch you towards a solution

    Thanks for the reply mawk!

    It's not exactly homework, Iv'e been trying Q= MC delta T and a few but then the flow rate throws me off (i'm thinking the flow rate may be a red herring) would I be correct?
