    Discretization of heat exchanger

    Hi. I hope my description of the problem will be sufficient. I'm trying to make an analytical model of a heat exchanger. The hex is a coil wound type, (helical coil) with several pipes in parallel to reduce the pressure loss, it is double. Meaning it takes it's turns (windings)...

    Heat exchanger

    At work, we have a tube and shell heat exchanger. The fluid to be heated is water and the other fluid is steam. -------------------------------------- Theoretical ... Btu / h: 136.1 x10 ^ 6 Flow Steam: 136,000 pph (I think it's pound per hour) Ti of the steam: 312 F To the steam: 212 F Psi...

    Heat exchanger conceptual question

    Hello everyone! I am trying to design a rankine cycle connected to a solar thermal power plant and a desalination power plant. Long story short, everything is almost done but I don't really understand the numbers I have. Meaning, the heat exchanger needs 154 MW to run the rankine...

    Heat exchanger energy equation and boundry conditions.. Help/advice needed

    Hello, I am a student currently working on my master thesis, the subject of which is the design and analysis of a heat exchanger. Because of some delays, bad luck and the calculations not leading where we (my promotor and me) hoped they would I am running a bit behind... The design part of...

    Heat Exchanger Design Problem

    Hi Guys, I'm an undergrad student undertaking an internship at the moment, and have been given the task of coming up with a way to cool down some fluid. Basically, I need to cool down a flow of 220L/min fluid from 45 to 38 deg C. Its thin black and a bit caustic with a PH of around 8, and...

    heat exchanger exergy analysis

    i am having a problem with heat exchanger (tube and fin) exergy analysis... the problem which i am having looks like this: in one of the cases air (mass flow of air: m,a=0,71 kg/s) is entering the heat exchanger with temperature T,aIN=21C and relative humidity RH,aIN=57%, air is cooled to...

    Heat Exchanger

    Cold water (cp = 4.18 kJ/kg.°C) leading to a shower enters a well-insulated, thin-walled, double-pipe, counter-flow heat exchanger at 15°C at a rate of 0.25 kg/s and is heated to 45°C by hot water (cp = 4.19 kJ/kg.°C) that enters at 100°C at a rate of 3 kg/s. Determine the rate of heat transfer...
