A petroleum crude oil having a density of 892Kg/m3 is flowing through the piping arrangement shown in the figure below, at total flow rate of 1.4103m3/s entering pipe (1). The flow divides equally in each of pipes (3). The diameter of pipes is (D1=0.052m,D2=0.078m,D3=0.040m) shown in the figure. Calculate the followings: 1. The cross section area in pipes (1), (2), (3). 2. The total mass flow rate in pipe (1), (2) and pipe (3). 3. The velocity in pipe (1), (2), and pipe (3)
