Jasim Review/Recap Sheet Q1- Answer with true or false and rewrite the false statements completely in correct form, otherwise no mark will be put on the false statements. 1 2 To represent a location on earth surface you need to define its altitude and longitude angles. 3 Solar zenith and solar incidence angles have the same value for horizontal surface. At sunset time the value of solar altitude angle is maximum. 4 The angle which represents the inclination of a given surface is the zenith angle 5 6 7 8 When the absolute value of sun-wall azimuth angle exceeds 90' this means that the sun rays are reaching the receiving plane. The solar irradiance and the solar irradiation have the same physical meaning. In the case of clear sky weather, the beam solar irradiation on a horizontal surface is less than the diffused irradiation. The total solar radiation received by a tilted surface is the same as that…

Direction: Graph the heating curve of ethanol using the information given. Check off each item as you add additional information to your graph so that none is missed.  Background information of Ethanol: Boiling Point = 78 0C Melting Point = -114 0C Starting Temperature = -120 0C After two minutes, frozen cold ethanol starts to melt. It takes two minutes to melt completely. After eight more minutes, it begins to boil. It boils for six minutes. Heat is added for two more minutes until ethanol reaches 80 0C. Label “melting” where this takes place. Label “vaporization” where this takes place. Label “phase change” where a phase change occurs. Indicate where ethanol is only a SOLID, only a LIQUID, and only a GAS. Of the three phases, label which phase has: weakest IMF, strongest IMF, and medium IMF.

Case Study: Paula’s Pain Paula has worked for Brindle Corporation for 3 years.  During this time, she has worked as a machine operator/cell leader in various work cells.  Recently, the plant went to mandatory 12-hour shifts and plans to remain on this schedule for several months. Paula’s present work cell is manufacturing 3-inch diameter exhaust tubes that are made from stainless steel.  These tubes get a hole punched in them, a flange welded on, and burrs ground off.  The pipe then gets placed into a gage to check that it was made correctly.  (The tubes weigh about six pounds.) Paula has been performing the welding operation.  She leans into the machine and loads the part into a fixture then positions the flange.  Both pieces are clamped (using hand clamps) into position and the machine is cycled by depressing two palm buttons. The gaging operation requires placing the finished part into the gage and clamping it (using hand clamps) into place. A pin is depressed to verify the position…
