WebDiameter of hemisphere = Edge of cube = 7 c m. Therefore, radius of the hemisphere = 7 2 cm. The total surface area of solid = Area of 5 sides of cube + CSA of Hemisphere + Face area remaining after the hemispherical part is removed. Area of 5 sides of the cube is 5a² = 5 × 7 2 = 245 c m ². CSA of hemisphere WebQuestion: A long 12-cm-diameter steam pipe whose external surface temperature is 90°C passes through some open area that is not protected against the winds. Determine the rate of heat loss from the pipe per unit of its length when the air is at 1 atm pressure and 7°C and the wind is blowing across the pipe at a velocity of 75 km/h.
