Forming and Shaping

Metal forming is a category of metalworking process through which the material can be given the desired shape and size by subjecting it to plastic deformation, where the component undergoes bulk deformation process upon application of loads. Unlike the shearing and machining process, the material does not undergo up to a failure point as indicated in the stress-strain curve. Hence, the stresses induced during the forming process are greater than yield strength but less than the failure strength of the material. The process does not lead to the loss of material, so it can be said to be an economical process. During forming, the material is subjected to tensile forces, compressive forces, bending, and shearing loading conditions. The material should possess the property of ductility to undergo the forming process.

A fixed-mass system contains mass, m = 1.0 kg of air. A thermodynamic process occurs from state one to state two, where T₁ = 300 °K, P₁ = 100 kPa; T₂ = 2700 °K, P₂ = 204.9953251 kPa. Determine S₂ - S₁ = m (S₂-S₁) in kJ / °K. Note: You are required to assume constant specific heats in this problem, with Cpo = 1.004 kJ/(°K * kg); for air, the gas constant is R = 0.287 kJ/(°K * kg).
A heat pump is used to maintain the interior of a building at 21 °C. At steady state, the heat pump receives energy by heat transfer from well water at 9°C and discharges energy by heat transfer to the building at a rate of 120000 kJ/h. Over a period of 14 days, an electric meter records that 1490 kW-h of electricity is provided to the heat pump. 1. Draw a schematic diagram(s)
