A pipe system to pump #6 fuel oil ( = 0.8 kg/m s, = 999.5 kg/m

Question:

A pipe system to pump #6 fuel oil (μ = 0.8 kg/m s, ρ = 999.5 kg/m³) consists of 50 m of 8-in, schedule-40, commercial-steel pipe. It has been observed that the pressure drop is 8.79 × 10⁴ Pa.

Determine the volumetric flowrate of the fuel oil.

Extra capacity is needed. Therefore, it has been decided to add a parallel line of the same length (neglect minor losses) using 5-

in, schedule-40, commercial-steel pipe. By what factor will the fuel oil volumetric flowrate increase?

50. There are three equal-length sections of identical 3-in, schedule-40, commercial-steel pipe in series. An increased flowrate of 20% is needed. How is the pressure drop affected? It is decided to replace the second section with two equal-length, identical sections of the original pipe in parallel. How is the pressure drop in this system affected relative to the original case? Neglect minor losses due to elbows and fittings and assume fully developed turbulent flow.
