Value of maximum rainfall for the central drain pipe of floating roof tanks
Thread Content
May I ask everyone, how is the maximum rainfall value for the central drainage pipe of floating roof tanks determined? Instantaneous maximum rainfall, daily average, monthly average, or annual average? There is no standard; where is the basis?
Investment based on the instantaneous maximum rainfall does not increase, ensuring safety.
Based on instantaneous maximum calculations, the central drainage pipe can meet the requirements under extreme conditions. Then doesn’t that emergency drainage device become a mere ornament?
The current issue is determining the diameter of the central drainage pipe, and this calculation requires the parameter of maximum rainfall. Don’t know how to choose?
Study*study*. It’s assumed to be the monthly average; waiting for experts to reply
