How to calculate the flow?

07/05/2008 3:01 PM

Fluid : Sodium Silicate 32baume temp of Fluid -90deg

I want to dose the Sodium Silicate with in 12Minutes. Level of Dosing Tank is 7mtr above ground level. Mixer is in 4mtr level. Means the Head of fluid is nearly 3mtr.

My question is

1.what diameter to be choose for this condition

<...what diameter to be choose for this condition...>

Make sure the average velocity in the pipe is <= 3m/s. If it is higher, the pipe is undersized.

You have mentioned 3m, but this is not the differential head but the head available with you to flow the liquid freely & if you do not use any means to flow the liquid then liquid has to flow with the help of gravity... so using Gravity 'figure' you can find out the velocity of fluid & A particular cross-section you can find out using 'Continuity Equation'. -Hope problem will be solved this way- Still as Frictional Losses you cannot imagine exactly as if you will reduce the cross-section frictional loss will increase, so you will have do at least one trial / test before finalising..
