A well is being drilled at a depth of 6,000 ft using mud having a density of 11 Ibm/gal, a plastic viscosity of 20 cp, and a yield point of 10 lbf 100 sq ft. The drillpipe has an external diameter of 4.5 in and internal diameter of 3.826 in. The diameter of the hole is 6.5 in. The mud is being circulated at a rate of 400 gal/min. Assume a relative roughness of zero. h) Determine the flow pattern in the drillpipe. i) Determine the frictional pressure loss per 1,000 ft of drillpipe. j) Determine the flow pattern in the drillpipe annulus. k) Determine the frictional pressure loss per 1,000 ft of annulus.
