### Evaluation of the Structure of Urban Stormwater Pipe

Keywords: urban ﬂoods; stormwater pipe network; drainage density; ﬂood risk 1. Introduction The frequency of torrential rainfall events has increased particularly in urban areas in South Korea [1]. Torrential rains in urban areas can cause temporal and local severe surface ﬂooding, which are commonly due to the lack of discharge capacity [2].

### Pump and piping sizing

a bigger pump, often it is easier to change the pipe or tube than to change the pump. In practice, to get the optimal system you have to select the pump capacity (i.e. flow rate) and head in conjunction with the right pipe or tube size to get the flow rate you intend at the destination.

### Submersible Pump Sizing & Selection

How to size a pump: What is required/desired flow? 5 GPM Determine TDH First, let’s calculate friction loss! Friction loss = total length X friction loss (straight pipe) factor + friction loss (fittings) Friction loss = ( 922 ’ X 1.8 ’/ 100 ’) + ( 3 ’ X 2 ) (1.8’/100’) Friction loss = 16.60 ’ + .108 ’
