Data are provided for steady-state operation of an electric motor in Fig. P6.56. Determine for the motor the rate of entropy production, in kW/K. Repeat for an enlarged system boundary such that the heat transfer occurs in the nearby surroundings at Tf 5 218F.
ME 270 – Lect. 2 – Design Process & DtC Four-Stages of Creative Thinking Process • Design Process 1) Preparation (stage 1): – The elements of the problem are examined and their interrelations • What is a “Product Design Specification” (PDS) are studied. Tradeoffs Boundaries Organize knowledge. 2) Incubation (stage 2): • Concurrent Engineering –“ Sleep on the proble
