there are several calculators out there on the web which work from liquid height rather than gas oil ratio: try one of these

MScarn hi
If you are using a VFD then presumably you are controlling the delta pressure. If you know the delta pressure across the pump the delta temperature is independent of the flowrate:
Wh = Q ΔP
Wi = Wh / e
Wi = m cp ΔT
m = Q ρ
Q ΔP / e = Q ρ cp ΔT
ΔP / e = ρ cp ΔT
ΔT = ΔP / (e ρ cp)
Wh...
download asme steam tables there seem to be plenty on the net.
otherwise you can calculate yourself using IAPWS R7-97

hi
it looks like the first pump would need to start slightly above 50 hz for 10 gpm. (round up to 51 hz as you say)
speed of one pump increases to 60 hz for 34 - 35 gpm
two pumps together start at 52 - 53 hz for 34 - 35 gpm
speed of two pumps increases to 60 hz approx 68 gpm
three pumps...
it looks like a towed pipeline installation. the pipe string is welded on land, and then the whole string is towed to its end location. the tanks provide buoyancy to stop it sinking. when the pipe is in place the tanks are slowly filled with water to lower the pipe to the seabed . first used by...
hi
there should be a code break somewhere at the landfall, usually at or close to the pig catcher or valve etc if there is one. F101 should be used right upto the code break. the landfall would probably be a similar location class to a platform riser.
consider pressure testing requirements...
use the moody diagram with friction factor calculated from pipe roughness and reynolds number. also weymouth, AGA and panhandle equations can be used.
try : http://pipeng.com/index.php/ts/itdmotflow006c/ for the moody diagram
the moody diagram can be used with either the darcy or fanning...
you could use the external collapse pressure calculation for submerged pipelines (pressure difference usually greater than 1 bar). gives the same result for external pressure or internal vacuum.
