Task P7 Use the continuity of volume and mass flow for an incompressible fluid to determine the design characteristics of a gradually tapering pipe Question P7.1 A tapered duct has an inlet diameter of 100mm and an outlet diameter of 80mm. If hydraulic oil enters the duct at a velocity of 5m/s, assuming incompressible flow, calculate (a) the volumetric flow rate in m/s (b) the mass flow rate in kg/s (c) the velocity of the oil at the duct outlet in m/s Task M3 Determine the up-thrust on an immersed body Question M3.1 A spherical metal ball weighing 4480g is dropped into a tank of water and displaces 500cm (a) Calculate the diameter of the ball (in cm) (b) Calculate the density of the ball (c) Using the density calculated, suggest a type of metal from which the ball may have been constructed. (d) Calculate the up thrust/buoyancy force on the ball
