56. •• Solar heating takes advantage of solar collectors such as in ▼ Figure 11.18. During daylight hours, the average intensity of solar radiation at the top of the atmosphere is about 1400 W/m2. On average, about 50%

reaches the surface. (The rest is reflected, scattered, and absorbed by the atmosphere.) Assuming a constant 700 W/m2, how much energy would be received, on average, by the cylindrical collector shown in the figure during 10 h of daylight?
