Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condit…

Textbook Question

Chapter 8, Problem 140P

Petroleum products are transported over long distances by pipelines such as the Alaskan pipeline (see Example 8.6). Estimate the energy needed to pump a typical petroleum product, expressed as a fraction of the throughput energy carried by the pipeline. State and critique your assumptions clearly.

In mechanical fluid

(a) Suppose we have planned to design a hydraulic system.ln this aspect, the pump selection is to be finalized for a flow rate of 3907 Liters per minute, It has been validated that the fluid velocity in a discharge pipeline should be between 4.4 m/s and 6.92 m/s. Calculate the minimum diameter and maximum diameter of pipe that should be used in the pipelines. (b) Write the significance of using minimum diameter pipelines in the hydraulic system. (a) Area of the maximum sized pipe diameter (in m?) (b) Area of the minimum sized pipe diameter (in m2) (c) The minimum sized pipe diameter (in m) (d) The maximum sized pipe diameter (in m)

Propose a centrifugal pump (brand and model) to transport 10 L/s of a fluid with a density of 1500 kg/m3 from a tank located on the first floor to a reactor on the second floor of the plant (8 meters in height). The reactor's operating pressure is 30 psig; the fluid is at 20 °C, and its viscosity is 15 cp. The pipeline on the pump discharge is 30 meters long (considering accessories are included). Neglect pressure losses in the pump suction. Propose the pipe diameter, schedule 40, commercial steel. Make any necessary assumptions. Select a pump capable of delivering a maximum flow of 15 L/s (remember that normal operation will be at 10 L/s) and discuss the price paid for this condition. Provide a copy of the pump curve indicating the operating point. Also, calculate the power consumption of the pump.
