FLUID MECHANICS - CASE STUDY
    Introduction


Problem Graphic

  A petroleum company is installing a wrought iron piping system to transfer crude oil from a well to a storage tank. The distance from the well to the storage tank is 9,500 ft. In order to minimize the pumping cost, the maximum tolerated head loss is 80 ft. The volume flow rate of the crude oil is 10 ft3/s. What is the required pipe size?
   
  Questions
 

Determine the required pipe size for the piping system using (a) Moody chart and (b) Colebrook correlation.

     
    Approach

 
  • The density (ρ) and viscosity (μ) of the crude oil are 1.67 slugs/ft3 and 1.8×10-4 lb-s/ft2, respectively.
