Plate HEX tutorial
• A plate heat exchanger was use to preheat 4 kg/s of dowtherm from 10 to 70◦C with a hot water condensate that was cooled from 95 to 60◦C.Determine the number of plates required for a single-pass counter flow plate and frame exchanger. Assume that each mild stainless-steel plate [kw=45j/s.m.K]has a length of 1.0m and a width of 0.25m with a spacing between the plates of 0.005m.Also,estimate the pressure drop of the hot water stream as it flows through the exchanger.
