please help

A concurrent flow double pipe heat exchanger using superheated steam is used to heat at the rate of 2.92 kg's. The steam enters the heat exchanger at 453 K and leaves at 405 K. The inlet and exit temperature of water are 303 K and 353 K respectively. If the overall heat transfer coefficient from steam to water is 814 W/mK. (i) calculate the heat (15) transfer area: (i) calculate the percentage increase in area if the heat exchanger has a co- Total 35
