Air enters a diffuser operating at steady state at 645°r, 15 lbf/in^2 with a velocity of 600 ft/s, and exits with a velocity of 60 ft/s. the ratio of the exit area to the inlet area is 8 assuming the ideal gas model for the air and ignoring heat transfer, determine the temperature, in °r, and pressure, in lbf/in^2, at the exit.

What difference(s) did you notice using a pneumatic circuit over hydraulic circuit. explain why the pneumatic piston stumbles when it hits an obstacle.

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.

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.
