7000 tonne/hr of water at 300 deg celcius flows through Steam generator tubeside to leave at 260deg celcius. How head loss due to friction & pressure drop due to shrinkage are taken in to account.

To begin you will need to first size the exchanger which of course will require you to choose a suitable type of exchanger for your application.
Only when these are available can you begin to calculate the pressure drop.

If a general 'guide' is required try Coulson and Richardson.

Dear rsk,
Your query appears somewhat 'vague' probably due to my incapability
What and how much is the other heated stream if your's reffered is (as appears) cooled stream?

thanks/regards

You need to design the heat exchanger, and in the design stage, you will need to calculate the pressure drop due to friction and so on. There is normally a range of acceptable pressure drop for the tube and shell side, if you are referring to shell and tube HE of course. For more information, you can refer to process heat transfer by Kern.

please refer to my edited post. flow of water is from tube side.
