For pipe cover calculation, Pipe cover = (Ground or Rim Elevation - Pipe invert elevation) - (pavement thickness) - (top of pipe thickness) - (pipe diameter). The formula for the volume of cylinder is: cylinder volume = * radius * height. It is based on the use of positive displacement pumps that are sensitive to suction line conditions, so the first couple of screens ask for information regarding the layout of the main tank(s) relative to the location of the pumps. Just type in diffferent sizes for same flow rate and same pipe length Extra equivalent pipe length due to fittings Barlows Formula is a calculation used to show the relationship between internal pressure, allowable stress (also known as hoop stress), nominal thickness, and diameter. Power vs, pipe diameter at 50-150 feet of head and 2000 feet of pipe. A particular pipe size on a given grade will only carry a certain amount of water.
