Activity 2 Problem 1. Select which of the piping installation you will recommend. An Industrial Plant requires 400 gpm of water to be delivered from a mainline where the pressure is 20 psig to an overhead tank 100 ft above the pump centerline. The following straight pipes and fittings will be used from suction to discharge. 2 pcs Length of straight pipe 120 ft Standard elbow 4 pcs Standard Tee Check valve 1 pc Globe valve Gate valve (fully opened) 1 pc Select between a 7 inches pipe and 8 inches diameter pipe. Show the power requirements for each, if the pump is to operate in 18 hrs/day 30 days a month. 1 pc Note: Table is available in other bond paper. 101 Example: The dotted line shows that the resistance of a 6-inch Standard El- bow is equivalent to approximately 16 feet of 6-inch Standard Pipe.
