Air flows steadily through an adiabatic turbine, entering at 150 psia, 900°f, and 350 ft/s and leaving at 20 psia, 300°f, and 700 ft/s. the inlet area of the turbine is 0.1 ft2. determine (a) the mass flow rate of the air and (b) the power output of the turbine.

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.

Hydraulic fluid with a sg. of 0.78 is flowing through a 1.5 in. i.d. pipe at 58 gal/min. the fluid has an absolute viscosity of 11.8 x 105 lbf-sec/ft2. is the flow laminar, turbulent or within the critical range? give both a numerical reynolds number and a term answer.
