Layout

The layout is a way of organizing the elements, products, and raw materials in a design. The layout is the representation of information in a structural, logical, descriptive, coherent form.The layout is a mapping of various equipment arrangements, workstations, machinery, plants, and more. It secures the continuous movement of a product quantity along with the quality.

Mechanical-Energy Balance and Friction Losses. Hot water is being discharged from a storage tank at the rate of o.223 ft3/s. The process flow diagram and conditions are the same as given in Example 2.10-6, except for different nominal pipe sizes of schedule 40 steel pipe as follows. The 20-ft-long outlet pipe from the storage tank is 1-in. pipe instead of 4-in. pipe. The other piping, which was 2-in. pipe, is now 2.5-in. pipe. Note that now a sudden expansion occurs after the elbow in the 13-in. pipe to a 2}-in pipe.
