The combination of a uniform flow and a source can be used to describe flow around a streamlined body called a halfbody. Assume that a certain body has the shape of a half-body with a thickness of \(0.5 \mathrm{~m}\). If this body is placed in an airstream moving at \(15 \mathrm{~m} / \mathrm{s}\), what source strength is required to simulate flow around the body?
