ALS manufacturers are involved in manufacturing, building, and assembling Offshore booster compressorunits, which include DNV skids and air receiver vessels, and they package everything in-house.To ensure quality control throughout the entire package preparation: no third-party manufacturers areused to assemble this booster compressor.As an engineer for the company, it is your task to design the air receiver vessel (pressure vessel) for theCompressor skid (as shown in the diagram) required for an offshore platform.This air receiver is used to store compressed air and is mounted vertically (See photo), the material used isan Aluminium alloy, and the Height of the Compressor skid is 10ft. See excel file “LO2 Data”Determine:1. The required material thickness (in inches) required for the air receiver shell.2. The required material thickness (in inches) required for the air receiver head.Note: According to the design standard, the head thickness = 2.5 x Shell thickness3. Based on the…

Please show system sketches and related energy flows for all problems. 1.a) Determine the electrical power supplied to a boiler when the temperature of the entering water is 20 C and the exiting temperature is 89 C. The flow of.the pressured water is 2 Kg/s. There is a negligible pressure drop through this boiler and it operates at a constant pressure of 3 bars. The specific heat is c = 4,370 J/(Kg K). There is a 1.5(105 ) W rate of heat loss from the boiler during this process to a surrounding at 293.2 k. Consider steady state conditions. 1.b) Calculate the total rate of entropy production 1.c) Calculate the total rate of exergy destruction (W).
