Please write clearly, show steps-formulas and if you need appendix in question write using values. Lastly, if you describe your solution, i will be happy.

Q) A counter flow concentric heat exchanger is to be designed to heat 0.25kg/s of water from 76C to 99C with saturated stean at 3.302 bar condensing in the outer amulus. The imer tube has 25mm atside and 21mm insde diameters. The thermal conductivity of the imer tuke is 110w/mk. If h=13000w2k i atthe required length of the heat exchanger b) stean thowrate in kg/h Q) A counter flow concentric heat exchanger is to be designed to heat 0.25kg/s of water from 76C to 99C with saturated stean at 3.302 bar condensing in the outer amulus.
