a) What regions show the largest oceanic latent heat loss? b) What regions show the saltiest surface waters? c) What is the main factor affecting the two radiation heat flux terms? Name the two fluxes.

Two water columns are at different temperatures, one being at 35°C and the other being at 18oC. The water columns are separated by a glass wall of area Im by 2m and a thickness of 0.005m. Calculate the amount of heat transfer. (Thermal Conductivity of glass is 1.6 W/mK) TABLE 13-13 Typical values of resistance for common building materials R, m K/W R for thickness shown, m K/W Building material Building board Eypsum, 9.5 mm particle board Building membrane 2 layers, 0.73 kg/ns³ felt 0.056 7.35 0.21 Glass single glazing. 3 mm double glazing. 6 mm air space triple glazing, 6 mm air space 0.16 0.32 0.47 Insulating material Blanket and batt mineral fiber from glass, approx. 90 mm approx. 150 mm approx. 230 mm approx. 275 mm glass fiber, organic bonded loose fill milled paper spray applied polyurethane foam Roofing 2.29 3.32 5.34 6.77 27.7 23 40 asphalt shingles buil-up, 10 mm 0.077 0.058 Masonry brick 1.15 concrete 0.6 Siding materials hardboard, 1l mm 0.12 plywood, 9.5 mm Aluminum or…
