assuming that the flow pattern is laminar flow rate of 200 gal/ min through a drill string having a 3.826-in. id and through an 8.5-x 5-in. annulus, calculate the required mud volume using 20% as volume safety factor given that depth of drill well = 10000 ft, length of drill collars= 500 ft, OD of drillingcollar= 6.5 in, ID of drilling collar = 2.25 in, casing setting depth = 5000 ft , case ID= 8.681 in, OD of drillpipes = 5in , ID of drillpipes = 3.826in


also it is desired to increase the weight of the mud from 12.0-lb/gal to 14.0-lb/gal mud. to keep the new mixture from becoming too viscous, 1 gal of water is to be added with each 100- lb sack of barite. a final mud volume of 700 bbl is required. determine the volume percentage of inital mud that should be discarded and the weight of barite to be added

Water flows through a shower head steadily at a rate of 8 kg/min. The water is heated in an electric water heater from 158C to 458C. In an attempt to conserve energy, it is proposed to pass the drained warm water at a temperature of 388C through a heat exchanger to preheat the incoming cold water. Design a heat exchanger that is suitable for this task, and discuss the potential savings in energy and money for your area.
