Prime factor in setting tray spacing is the economic trade-off between column height and column diameter. Determine the rainfall intensity using the Rational Method. 0.1 cfs maximum flow allowed to bypass last inlet (Qbp) Shell diameter =22 inches.Allowable width of flow (flow spread or Zd allowable).Roadway longitudinal slope and transverse (cross) slope.Catchment area or pavement draining to inlet being designed is defined by begin/end station and roadway width.Select a suitable type of shell and tube exchanger. Compute the inlet spacing and compare to the trial value.Compute the interception coefficient, K.Table of Contents Item Page # South Carolina Outline Map 3. Define design parameters such as - number of tube passes, tube size, shell ID etc. Calculate Grid Spacing on iPhone and Androidâ„¢ Now you can compute wall spacing while at your desk or while on the road with the Y+ Calculator for iPhone, iPad, or Android. Request a Quote 15.2 Inlet Locations Maximum Spacing: Water should normally not travel more than 300 to 600 feet before interception, with the closer spacing employed for flat terrain and for high-speed highways.
