For a circular horizontal curve with I = 12 degrees, R = 1200 ft, and Pl at Station 2+41.8, the stationing of the PC and PT, respectively, would be:
O 1+16.9, 3+68.2
O 1+25.6, 3+76.9
O 1+15.7, 3+67.0
O 1+15.7, 3+65.8

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

If you were designing a bumper for a car, would you prefer it to exhibit elastic or plastic deformation? why? consider the functions of a bumper in both a minor "fender-bender" and a major collision.

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.
