OPTIMISATION OF FLUID VELOCITIES IN SHIP'S PIPING SYSTEMS

Optimum velocities are shown to be primarily a function of the ratio of pipework cost to head loss, together with the system usage factor and certain basic cost data. Recent disproportionate increase in fuel costs has reduced the velocities for minimum life cycle costs by about one quarter. Approximate values of optimum velocity are calculated for several typical engine-room pipework systems.
