1. Consider a design of a low-speed open-circuit subsonic wind tunnel. The goal is to achieve a free stream velocity of 150 m/s at the test section of this tunnel. This wind tunnel is equipped with a U-tube mercury manometer that measures the pressure difference between the inlet (the settling chamber) and the test section. If the fan of the wind tunnel is able to generate the maximum pressure difference corresponding to a height difference of 10 cm on the...

The closed-circuit wind tunnel flows air with a velocity of 200 fu's (between sections (5) and (6)] at standard condition. The picture and diagram of the wind tunnels are provided below. The flow is driven by a fan that essentially increases the static pressure by the amount Pi-P that is needed to overcome the head losses experienced by the fluid as it flows around the circuit. Determine the pressure rise ( P P ) Conditions) Assume air is incompressible (Mach...
