Mechanical engineering : Heat transfer 1. Determine the overall heat transfer coefficient and flow rate required while using a heat exchanger , the water is enetered at 20◦C through the tubes of small single pass and the water comes out with a temperature at 40◦C. 25 kg/min of steam condenses at 60◦C on the shel side ,the area of the exchanger is 12 m2. (The latentheat, hfg, is 2358.7 kJ/kg at 60◦C.) 2 . You have unpainted aluminum siding on your house and the engineerhas based a heat loss calculation on U = 5 W/m2K. You discover thatair pollution levels are such that Rf is 0.0005 m2K/W on the siding.Should the engineer redesign the siding? If not sure skip, wrong may downvote
