A 300 ft-long 6-ft-wide parabolic trough concentrator receives normal sun radiation at 905 W/m2. A pipe at the focal line received 450 lbm /hour of water at 200 psia and at 100 oF and exits at 180 psia. Calculate the pipe exit conditions. Assume the concentrator reflective losses of 5 percent.

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

Apiston-cylinder device contains 0.1 m3 of liquid water and 0.9 m3 of water vapor in equilibrium at 800 kpa. heat is transferred at constant pressure until the temperature of water reaches 350 °c. determine (a) the quality of water at the initial state (b) the work associated with this process, (c) the heat associated with this process.

In general, how do thermosetting plastics compare to thermoplastics in mechanical and physical properties?
