Aerospace Engineering > GATE 2023 > Potential Flow
In a potential flow, a uniform stream of strength U directed along the x-axis and four line sources (2-dimensional) of strengths π/2, π/4, π/5, and -π/5 are placed along the x-axis at x = 0, 1, 2, and 3, respectively. The strength of an additional line source to be placed at x = 4 such that a closed streamline encircles all five sources is _______. (round off to two decimal places)
