Amodel test of a tractor-trailer rig is performed in a wind tunnel. the drag force, fd, is found to depend on the frontal area, a, wind speed, v, air density, r, and air viscosity, µ. the model scale is 1: 4 (e. g., 1 m in the model is equivalent to 4 m in the prototype), frontal area of the model is a = 0.625 m2 . a. obtain a set of dimensionless parameters suitable to characterize the model test results

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
