you have first to know the thermal conductivity of PPR that you are dealing with. normally, this is in range between 0.1 to 0.24 W/MK .then you apply this formula Q(IN WATTS) =Thermal Conductivity/MK)*A( surface area for the pipe M2 )temperature difference between fluid inside pipe and temprture of pipe surface K)/(thickness of the pipe M)
The open channel flow has a free surface whereas the pipe flow has a closed surface.
For every vertical foot of pipe, take that and multiply it by .434.This equation will get within 1/2 -1/4 psi.
There is no such formula

50nb ms pipe unit weight
what is weight of 60 dia ms pipe
Weight of pipe per Meter in Kg for MS Pipes = 3.14 * (Outer diameter of pipe in Mtr. - wall thickness in Mtr. ) * Wall Thickness in Mtr. * 7850
