A sprue in a sand mould has a topdiameter of 20 mm and height of 200mm. The velocity of the molten metalat the entry of the sprue is 0.5 m/s.Assume acceleration due to gravity as9.8 m/s2 and neglect all losses. If themould is well ventilated, the velocity(upto 3 decimal points accuracy) of themolten metal at the bottom of the sprueis ______ m/s.
A component is sand casted in pure aluminum. The level of the metal inside a pouring basin is 215 mm above the level of the metal in the mould. For a viscosity value of 0.0017 Ns/m² and a circular runner with a diameter of 11 mm, calculate: 2.1 The velocity and rate of flow of the metal into the mould. 2.2 What effect does turbulent flow in a gating system have on the casting? 2.3 Which measures can be implemented to reduce turbulent flow?
Q.B3. As part of a project, students have been asked to cast an Aluminium disc for use as a flywheel. The flywheel is part of an engine development project and needs to be 200 mm in diameter and 20 mm thick. Green sand casting will be used. The shrinkage associated with this metal and process is 5% at the solidification stage and further 3 % on cooling to room temperature. Aluminum has a density of 2710 kg/m³ and a melting temperature of 660°C. The pouring temperature is 700°C while the specific heat of aluminum is 887 J/kg.K. The latent heat of fusion of Aluminum is 396 kJ/kg. From previous experiments the Chorinov constant for the mold was found to be 10 s/mm². Determine: a.) The dimensions of the pattern (diameter and thickness) that will need to be made for this part (ignore riser and sprue). b.) The time it will take for complete solidification of the part. c.) Assuming an electric furnace at 10% efficiency is used to heat the metal and it takes around 2 hours achieve pouring…
2. A 10-inch x 10-inch x 0.75-inch plate casting is produced with a steel alloy with p = 0.28 lb/in³ (= 7.75 g/cm³). Two third of the steel plate casting volume should be added more into the original one, and all molten metal should be poured in 10 seconds. The cylindrical, tapered sprue height is 4 inches. The sprue has a cylindrical base and is connected to two runners. Each runner with a square vertical cross-section is connected to two gates. The gate has a rectangular vertical cross-section, and its width is three times the height. 0.75 inch Cylindrical Square Rectangular sprue base gate runner Steel alloy casting Note that drawings are not to actual scale or ratios. Area of a sprue base's horizontal cross-section The ratio of the cylindrical sprue base's horizontal cross-sectional area to the sum of two runners' vertical cross-sectional areas to the sum of four gates' vertical cross-sectional areas is 1:2:3.

A pure aluminum is being poured into a sand mold. The metal level in the pouring basin is 10 in. above the metal level in the mold, and the runner is circular. What runner diameter is needed to ensure a Reynolds number of 2000? how long will a 20 in' casting take to fill with such a runner? given that Pure aluminum has a density of 2700 kg/m' and a viscosity of around 0.0015 N.s/m2 at 700 °C. Use v 87.9 in/s 2.23 m/s for the Reynold number. (
In the following set of questions, we will consider a mercury-in-glass thermometer. The tworeference points will be assigned 0.01◦C and 100◦C based on the triple point and boiling point ofwater. a) Remark on the the rationale for selecting references based on phenomena such as phase transi-tions. Identify any prospective issues or special considerations one might have with this approach? b) Draw a schematic of a mercury-in-glass thermometer. Define an appropriate set of universe,system, and surroundings and explain the functional operation of thermometer from a thermody-namic analysis perspective.
