QUESTION 3
Oil (SG = 0.76) is flowing into the tank shown below with an average velocity of 4 m/s through the 50
mm diameter pipe at A. It flows out of the tank at an average velocity of 2 m/s through the 20 mm
diameter pipe at B.

a) Selecting the control volume to include the entire tank contents, write the general form of the
mass balance equation for the oil in the tank.
b) Calculate the volumetric flow rate (m³/s) of oil that is entering via the pipe at A.
c) Simplify the expression in part a) to determine the numerical value for the rate at which the level
(h) of oil in the tank is changing.
