    Anyone out there give me a hand here? This is the first task my company has asked me to do for them. "Please could you determine pipe schedule for the following arrangement: 4940 level (4940 ft) pipe entry point into No 4 shaft, flow 120 l/s. Assume Sch. 40 pipe. 5900 level (5900 ft) intermediate level with BAC using 60 l/s 6500 level (6500 ft) intermediate level 7500 level (7500 ft) intermediate level 8500 level (8500ft) bottom level using 60 l/s Please could you use the ASME B31.3 piping code to specify the pipe schedule changeovers and recommend a pipe support strategy. Assume Victaulic pipe couplings type 77 are used. For 80 Sch and above piping type 808 couplings (double grooved type ) will be used. Please assume the pump peak pressure bottoms out at 600 kPa. Please do the calculation with and without a water hammer allowance in the design pressure variable." Any help would be great! Thanks

      You will be needing ASME B31.4 or B31.8 instead B31.3 (it seems you are dealing with a pipeline)... you will also need design Pressure and Temperature in order to calculate minimum wall thickness (Mechanical Design).

      The hydraulic data you have will allow you to determine the optimum hydraulic diameter (considering flow speed and friction losses) and ASME's piping Codes (Serie B31) does not cover that issue... only mechanical design.
