A pump that works at 5kW delivers brine with a density of 1150kg/m³ from the bottom a supply tank to the bottom of another tank at a velocity of 3.25m/s. The discharge in 1.10m above the supply and the line between the two open tanks in 45m. The line consists of elbows, tees and valves and you have calculated that the total form friction from these fittings and valves is 2.45 J/kg. you have also determined that the skin Darcy friction factor is 0.03. If the pump is 80% efficient and you assumed that flow is incompressible, what is the pipe internal diameter in cm.

Question
Transcribed Image Text:A pump that works at 5kW delivers brine with a density of 1150kg/m3
from the bottom a supply tank to the bottom of another tank at a
velocity of 3.25m/s. The discharge in 1.10m above the supply and the
line between the two open tanks in 45m. The line consists of elbows,
tees and valves and you have calculated that the total form friction
from these fittings and valves is 2.45 J/kg. you have also determined
that the skin Darcy friction factor is 0.03. If the pump is 80% efficient
and you assumed that flow is incompressible, what is the pipe internal
diameter in cm.
