Metal Casting

Metal casting is described as a manufacturing process in which a mold cavity is produced by sand, and molten metal is filled inside a mold cavity. The desirable shaped object is achieved after the solidification of molten metal. Large metal objects like machine beds, motor bodies, and others can easily be manufactured using metal casting. The place or shop where metal casting is performed is called foundry.

What is Shear Flow?
Pure aluminium is poured into a sand mold. The metal level in the pouring basin is 203.2mm above the metal level in the mold, and the runner is circular with a 7.62 mm diameter.What is the velocity and the rate of flow of the metal into the mold? Is the flow turbulent orlaminar? Note that pure aluminum has a density of 2700 kg/m3and a viscosity of 0.004Ns/m
A cold rolling operation is to be used to reduce a 50 mm thick and 200 mm wide copper plate. The entering velocity of the plate is 15 m/min and the exit velocity is 18 m/min. The coefficient of friction is 0.2 and assuming that the reduction in thickness during this process is the maximum draft permissible. If the plate widens by 5% after rolling, calculate the power required to drive the rolls. Assume average flow stress of the material as 180 MPa.

Define the term Shear Flow?
Merrill et al. (1965) in a series of classic experiments studied the flow of blood in capillary tubes of various diameters. The blood had a hematocrit of 39.3 and the temperature was 20°C. They measured the pressure drop as a function of the flow rate for five tube diameters ranging from 288 to 850 μm. When they expressed the measured pressure drops in terms of the wall shear stress, and the volumetric flow rates in terms of the reduced average velocity, all of the data for the various tube sizes formed, within the experimental accuracy, a single line as predicted by the Rabinowitsch equation expressed in terms of reduced average velocity. From their results they provide the following values of the Casson parameters at 20°C: τy = 0.0289 dynes cm−2 and s = 0.229 (dynes s cm−2)1/2. Using these values for τy and s, show that the equation below for reduced average velocity provides an excellent fit to their data summarized in the following table. (Wall shear stress) τw , dynes cm-2…

Answer should be not so long. Need Straight forward answer! By considering a notched metal bar as an example, explain (with the aid of diagrams), how you would reduce the probability of fatigue failure by applying self-stresses. Also Describe, with sketched examples, how the stress-raising effect of circular and elliptical holes can be considered qualitatively as being analogous to liquid flow.
A large plate is pulled at a constant speed of U = 4 m/s over a fixed plate on 5-mm-thick engine oil film at 20°C. Assuming a half-parabolic velocity profile in the oil film, as sketched, determine the shear stress developed on the upper plate and its direction. What would happen if a linear velocity profile were assumed?
