Consider the inviscid, incompressible flow of air along a streamline. The air density along the streamline is 0.002377 slug/ft3, which is standard atmospheric density at sea level. At point 1 on the streamline, the pressure and velocity are 2116 lb/ft2 and 10 ft/s, respectively. Further downstream, at point 2 on the streamline, the velocity is 190 ft/s. Calculate the pressure at point 2. What can you say about the relative change in pressure from point 1 to point 2 compared to the corresponding change in velocity?
