Aship 90 meters long is floating on an even keel at 6 m draft. the half-ordinates, commencing from forward, are as follows: 0, 4.88, 6.71, 7.31, 7.01, 6.40, and 0.9 m respectively. the half-ordinates 7.5 meters from bow and stern are 2.13 and 3.35 m respectively. the change in draft if 153 tonnes of cargo are loaded with its center of gravity vertically over the center of flotation. find the water plane area (wpa); and lcf from the aft perpendicular.

Consider a 1.2 meter high and 2 meter wide glass window whose thickness is 6 mm and thermal conductivity is 0.78 w/m °c. the room temperature is maintained at 24 °c, while the outdoor temperature is -5 °c. the convective heat transfer coefficients on the inner and outer surfaces of the window are 10 w/m2 °c and 25 w/m2 °c respectively. (a) draw the thermal resistance network, etermine the steady rate of heat transfer t e glass window (c) determine the temperature of the inner surface of the window
