Oil with a specific gravity of 0.892 flows through a piping system and enters pipe 1 at a rate of
1.388\times 10^(-3)(m^(3))/(s)
as shown in Figure 4.1. The flow divides equally in pipes 3 and 4. Evaluate: 4.1 The total mass flow rate in the pipes 1 and 3 . (10) 4.2 The average velocity in 1 and 3 . 4.3The mass velocity in 1. (4) (2)
