Question

A water tunnel test section has a 1-m diameter and fl ow
properties V = 20 m/s, p =100 kPa, and T =20°C. The
boundary layer blockage at the end of the section is 9 percent.
If a conical diffuser is to be added at the end of the section to
achieve maximum pressure recovery, what should its angle,
length, exit diameter, and exit pressure be?
