4. A valve with diameter of 60 cm is intended for applications with water (kinematic viscosity v 9.96-107 m2/s) in the range of mean water velocities between 1 m/s and 2.5 m/s. The performance of this valve is to be determined from tests on a scaled 30-cm-diameter valve with atmospheric air(v-up = 157 105 m2/s). What range of mean air velocities in the smaller valve is required to model bigger valve operating with water? Note: Viscous forces are important.
