A piston-cylinder device initially contains 1000 liters of water at 2500 kPaa and 210°C. Heat is added to the water at constant pressure until the temperature becomes 300°C. Determine: a. The properties of water at the initial condition; b. The condition of steam after the addition of heat; C. The properties of steam after the addition of heat; and The work done and the heat added. d. [Ans. a) v, = 1.1691 x 10 m/kg, u, = 893.0 kJ/kg, h, = 898.8 kJ/kg. S₁ = 2.3255 kJ/kg-K; b) Superheated steam; c) v₂ = 98.90 x 10³ m³/kg. u₂ = 2761.6 kJ/kg, h₂ = 3008.8 kJ/kg, s, = 6.6438 kJ/kg-K; d) W = 208 987.5 kJ, Q=1 804 809.6 kJ]

Provide any six important skills required for the design of plant layout and piping design.

Solution 1: Ergonomic Assessment and Improvement. An ergonomic assessment of Paula's workstation could identify areas where adjustments could be made to reduce strain on her wrists. This could include adjusting the height of the workstation, providing wrist supports, or changing the design of the tools she uses. The strength of this solution is that it directly addresses the physical strain causing Paula's discomfort. However, the weakness is that it may require investment in new equipment or tools, and the effectiveness will depend on the specific changes made. Solution 2: Job Rotation. Paula could be rotated between different tasks more frequently, reducing the amount of time she spends on tasks that strain her wrists. This could also include training other workers to perform the welding and gaging operations, allowing for more flexibility in task assignments. The strength of this solution is that it reduces the repetitive strain on Paula's wrists. The weakness is that it requires…

One critical consideration to achieve accurate cost estimate is: All of the given options The product has been simplified as much as possible through DFMA Cost should be estimated as soon as the first design concept is genera At least three design concepts are generated
