Ollivander sells sheets of aluminum in a variety of thicknesses: 1.0 mm at 0.55 $/cm2, 2.0 mm at 0.70 $/cm2, and 3.0 mm at 0.85 $/cm2and various thicknesses in between all following the same linear trend. Harry needs 10.0 cm2of 2.2 mm thick aluminum. How much does this cost him

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.

Burgers vector is generally parallel to the dislocation line. a)-true b)-false

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
