At the point of confluence of two tributary streams, assumed vertically mixed, the difference in water temperatures is 15◦. Both streams have a flow velocity equal to 0.5m/sec, a depth of 1m, and a thermal diffusivity coefficient equal to 0.01m2/sec. Estimate the difference in temperature between two points 100mdownstream of the confluence, and 10mon each side of the main river’s centerline.
