class i series pipe line systems
Class I: Series Pipe Line Systems
  • hL = Energy losses due:
  • Pipe friction
  • Minor losses
    • Valves
    • Exit and entrance losses
    • Enlargements/Contractions
    • Bends/elbows
class i example
Class I: Example
  • Calculate the power supplied to the pump in Fig. 11.2. The pump is 76% efficient, methyl alcohol flows at 0.015 m3/sec at 25° C. The suction pipe diameter is 102.3 mm, and 15 m long. The discharge pipe diameter is 52.5 mm, and 200 m long. The entrance is square-edged type, the elbows are standard and the globe valve is fully open.
class ii example
Class II: Example
  • Oil flows in 6-in pipe (SCH 40) steel pipe with a pressure drop of 60 kPa per 100 m. S.G. = 0.88, m = 9.5 x 10-3 Pa-sec. Determine the flow rate.
example
Example
  • A lubricating oil needs to be pumped from 1 to 2 with a maximum pressure drop of 60 kPa. The oil’s S.G. is 0.88, m = 9.5 e 10-3 Pa-s. Determine the flow rate, class type and solution method.
