Calculate Friction Loss for Irrigation

[DGM_Jakarta]

Dear All,

I have a project for Irrigation plant a rice seeds that need calculation of friction loss, I tried the freecallculator, but not sure if its correct. I have two problem and The problem are for case 1 & 2 because each pump for case 1 & case 2 are different.

1. Diameter of the pipe : 20"

Material of pipe : PVC

Length of pipe : 1600 Metre Horizontal

Elevation : 5 Metre

Flow rate that i use : 300 Litre/second

Pressure at : 1,5 Bar

After that i used reducer and add another Pump for :

Diameter of the pipe : 16"

Material of pipe : PVC

Length of pipe : 1035 Metre Horizontal

Elevation : 1 Metre

Flow rate that i use : 150 Litre/second

Pressure at : 4 Bar

Can anyone help me count the friction loss pleaseeeeeeeee, i need urgently

2. Diameter of the pipe : 20"

Material of pipe : PVC

Length of pipe : 2100 Metre Horizontal

Elevation : 5 Metre

Flow rate that i use : 300 Litre/second

Pressure at : 1,5 Bar

After that i used reducer and add another Pump for :

Diameter of the pipe : 16"

Material of pipe : PVC

Length of pipe : 1740 Metre Horizontal

Elevation : 0 Metre

Flow rate that i use : 150 Litre/second

Pressure at : 4 Bar

Can anyone help me count the friction loss pleaseeeeeeeee, i need urgently

and how much losses at PVC Tee 20", PVC Elbow 20", Gate Valve cast iron 20".

Thank you very much... please... please.... somebody... helppppp

Pick up a copy of Cameron Hydraulic Data - it has most everything you'll need for hydraulics. I don't have my copy in front of me or I'd check some numbers for you.
