5. Compute the equivalent mud density in the annulus if the mud density entering the well is 9 Ibm/gal and the ROP is 100 ft/hr. Assume a vertical wellbore and a flow rate of 600 gal/min, a bit size of 9.875 in., a pipe OD of 7 in., and a rock bulk density of 2.2 g/ cm3 (HINT: compute cuttings concentration first).
