Q 122.
Describe the methodology for a project report of a compressed air system for a plating workshop, in which two sanders, two spray guns (used in the painting area) and two polishing machines (used in the polishing area) are not used.
The total flow rate of the system, which will be used to size the compressor, is the sum of the flow rates required by these pneumatic tools described above.
The permissible pressure loss of the system was considered to be 0.3 bar and the working pressure of the system was considered to be 6 bar.
The total length of the pipe in each area is calculated by adding the linear length of the pipe to the equivalent length of the accidents.
The slope of the pipe was adopted as 2%, with the objective of condensate drainage
With this data, the diameter of the pipe in each area of the workshop is calculated using the attached formula

- As shown in the picture blew, a pump can deliver volume flow rate of of water through a vertical lift of . The inlet to the pump is just below the water surface and the discharge is to the atmosphere through a DN50 schedule 40 steel pipe. The energy loss . (1) Calculate velocity at the exit of point 2__________m/sarrow_forwardProblem 2 A pump is needed in a water supply system. The water is being pumped out of a ground-level storage reservoir with water surface elevation of 149.27 ft and needs to pass over a hill 2 miles away, where the pipe centerline is at elevation 200.00 ft. The flowrate is 22 mgd, pipe diameter is 24 inches, Hazen-Williams friction factor is 110, and pressure at the crest of the hill must be at least 20 psi. (a) What head must the pump provide? (b) How much power will be added to the water? (c) What size motor should be purchased if the pump/motor combination has an efficiency of 80 percent?arrow_forwardFor the hydraulic system of Figure 8, the following data are given: The pump is adding2.984kW to the fluid.(a) Pump flow is 0.00158 m3(b) The pipe inside diameter is 0.0254m.(c) The specific gravity of the oil is 0.9.(d) The oil tank is vented to the atmosphere.(e) The head loss HL between station 1 and 2 is 12.19m.(f) The elevation difference between stations 1 and 2 is 6.096m.Find the pressure available at the inlet to the hydraulic motor(station 2).arrow_forward
