10. What is Centrifugal casting?

The velocity of the air is tripled in the problem above to 38.1 m/sec to increase the heat transfer rate from the mold. Calculate the new heat transfer rate (q).

Is the system in steady state or unsteady/ transient statewhen you dry the bagasse fibers and put them on the rolling mill with the plastic and put them in a compression molding machine to produce the product?

We have a machine called candle making machine using pneumatic press, what is the formula for determing the pressure that we need? What are the consideration?

where are the steps for the solution?????

2. Assignment You are tasked to investigate the following and to compile your findings in a technical report: 2.1 What is the benefit of using investment casting for the production of a turbine rotor compared to other casting processes? 2.2 Which AM materials and processes (according to the ISO/ASTM 52900 standard) is mostly used during the manufacturing of patterns for the investment casting process? List the advantages and disadvantages of each of the AM processes. 2.3 What are the advantages and disadvantages of using AM techniques to produce patterns for the investment casting process, compared to conventional methods? 2.4 Show with a sketch, how the build orientation of the processes listed in Question 2.2 can have an influence on the accuracy and surface quality of a pattern. 2.5 Which manufacturing process (listed in Question 2.2) will be most suitable to produce a pattern for the turbine rotor? Provide reasons for your selection. 2.6 The use of additive manufactured patterns…
