Head Loss Calculator

[eMerlino]

I found this website with a free calculator:

http://arash.dejkam.com/software/pressure_loss/

This looks good, but the head loss values seem low.
When I calculate head loss by hand I get much larger values.

Is this calculator valid, and why am I getting such larger values by hand calcs? (Darcy and H-W)

Thanks.
