2. (2 points) Locate the centroid and calculate the moments of inertia for a “T” shaped beam that consists of a stem (the upright piece) that is a “2x8” and the flange (the piece across the top) that is a “2x6”, centered on the stem. Note that a “2x6” has actual dimensions of 1-1/2”x5-1/2” and a “2x8” has actual dimensions of 1-1/2”x7-1/2”.

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.

The higher the astm grain size number, the finer the gran is. a)-true b)-false

Atank with constant volume contains 2.27 kg of a mixture of water phases (liquid-vapor). in the initial state the temperature and the quality are 127 °c and 0.6, respectively. the mixture is heated until the temperature of 160 oc is reached. illustrate the process in a t-v diagram. then, determine (1) the mass of the vapor in kg at the initial state, (2) the final pressure in kpa.
