Problem 2 (a): A mold has a downsprue of length - 6.0 in. The cross-sectional area at the bottom of the sprue is 0.5 in'. The sprue leads into a horizontal runner that feeds the mold cavity, whose volume = 75 in'. Determine (a) the velocity of the molten metal flowing through the base of the downsprue, (b) the volume rate of flow and (c) the time required to fill the mold cavity. Problem 2(b): The total solidification times of...

Consider casting sand mold of the piece shown in the figure. The
dimensions are in centimeters.
(i) The molten metal overflows the pouring cup of the mold and
flows down the sprue (downsprue) at a constant rate of 2000
cm3/s. The cross section of the sprue is circular, with
a diameter of 6 cm at the top....

A section of glass tubing has three different cross sectional areas, A1, A2, A3, which are in decreasing order. Fluid is continuously pushed the tube at a constant rate. Narrow vertical columns of identical diameters are inserted into the tube at each of the three different sections to measure the hydrostatic pressure. Fluids i nmotion at the same elevation follow Bernoulli's equation. 1. What is your prediction of pressure readings ? Is it p1 < p2< p3 2. Section 2...
