drainage - How do I measure the discharge from a Sump Pump

A discharge pipe 18" above the ground is unusual. If it''s discharging right at your house, some portion of the water will seep back to the foundation no matter how much slope you have. If it is discharging a good distance away, you''ve got a pipe at a height where it''s a trip hazard and exposed to damage.

Sizing Up a Sump Pump

10.5 feet of equivalent pipe, while the check valve adds 11.5 feet. The total equivalent feet Step 2. Determine the Actual Pipe Length The actual pipe length is the length of pipe running horizontally out of the house. You should be able to see where the pipe discharges outside of the house. Example: In our example, the length of discharge pipe is 100 feet.

Main principles of pumps selection. Calculation of pumps

Teeth transfer fluid inside pump body, and then it is squeezed to discharge pipe at the time when teeth engage again. For flow of pumped fluid the gear pumps are provided with end and tooth tip clearances between body and gears. Gear pump performance capacity can be calculated in the following way: Q = 2·f·z·n·b·η V

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 ’
