Air flows through the venturi meter described in the previous example. Assume

Air flows through the venturi meter described in the previous example. Assume that the upstream pressure is 413 kPa, and that the temperature is everywhere constant at 20 C. Determine the maximum possible mass flow rate of air for which the assumption of incompressible flow is a valid engineering approximation. Compute the corresponding differential pressure reading on a mercury manometer. D D Flow
