The temperature at the point (x, y, z) in a substance with conductivity K = 5.5 is u(x, y, z) = 3y2 + 3z2. Find the rate of heat flow inward across the cylindrical surface y2 + z2 = 7, 0 ≤ x ≤ 5.
The temperature at the point (x, y, z) in a substance with conductivity K = 5.5 is u(x, y, z) = 5y2 + 5z2. Find the rate of heat flow inward across the cylindrical surface y2 + z2 = 7, 0 ≤ x ≤ 2.
