From time t=0 to t=5 hr radioactive steam is released from a nuclear power plant located at x = -1 mile and y = 3 miles. The following wind conditions are expected: V = 10 i - 5 j mph for 0 < t < 3 hr, V = 15 i + 8 j mph for < t < 10 hr, and V = 5 i mph for t > 10 hr. Draw to scale the expected streakline of the stream for t = 3, 10, and 15 hr.
