- Draw a simple flowchart of a hypothetical oxygen piping system, which has two branches with diameters different from the diameter of the main branch, containing the following components: 1 pressure swing adsorption (PSA) generator. 1 compressor to pressurize the oxygen that will be transported in the tubes. 1 storage tank to retain oxygen before use. 1 industrial combustion process to serve as an energy consumer 2 heat exchangers to control the oxygen temperature. 4 pumps to move oxygen through the piping system. Required quantity of pressure relief valves, flow valves, drains and vents.arrow_forwardIndustrial piping system Develop a flowchart of a hypothetical industrial piping system (or a real example), in which the fluid is water, explaining the processes and listing and quantifying the equipment (boilers, heat exchangers, flow valves, relief valves, traps, installed machinery, drains, vents...) Also Set: The maximum design pressure, which would be the MAOP (old and hot), the maximum and minimum operating pressures; The diameters of the branches, considering that there is one main branch and at least two secondary branches; Define the specification of the material used in the pipe; Define a temperature; Finally, indicate the appropriate locations for the installation of relief valves, traps, drains, vents and flow valves.arrow_forwardAn air-conditioning system is designed to have a ductwith a rectangular cross section 1 ft by 2 ft, as shown. Duringconstruction, a truck driver backed into the duct and made it atrapezoidal section, as shown. The contractor, behind schedule,installed it anyway. For the same pressure drop along the pipe,what will be the ratio of the velocity in the trapezoidal duct tothat in the rectangular duct? Assume the Darcy-Weisbach resistance coefficient is the same for both ducts.arrow_forward

- Problem 1: Fresh water at a temperature of 10°C flows at a rate of 0.10 m3/sec through the piping system sketched above. The system consists of 30 meters of 150 mm diameter (I.D.) galvanized iron pipe, 4 regular 90-degree threaded elbows, and a swing check valve which may be assumed to be in the forward flow position. The elbows and the inlet and outlet of the check valve are 150 mm I.D. also. The elevation of Station A is 2 meters higher than Station B, ?? −?? =2?.
