5. A sprue is 200 mm long. The velocity of the molten metal at the top of the sprue is 0.1 mm/sec. The sprue has a diameter of 10 mm at the bottom. The total cavity of the "runner system + mold" is 1.2 liters. The viscosity of the molten metal is 0.002 Pa. s and density 2000 kg/m 3. a) What is the velocity of the molten metal at the bottom of the sprue in [mm/s]? b) What is the flow rate in [mm3/s]? c) How much time does it take to fill the mold? d) For a proper design, what should be the diameter of the sprue at the middle (corresponding to z= 200/2 mm) of the sprue? e) Is the flow laminar, mixed, or turbulent at the bottom of the sprue? h++ Pg Zg constant 2 = Av = Av.

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.
