1) Which of the following statement is NOT correct about piping network?a)In parallel pipes, the flow rate is proportional to its diameter and inversely proportional to its length and friction factor.b)When analyzing the piping network, conservation of mass throughout the system must be satisfied.c)In piping systems with pumps, the Bernoulli equation should be corrected by introducing a kinetic energy correction factor.d)The algebraic sum of head losses for all loops equal to zero.2) The EGL is always a distance V2/2g above the HGL. True or False

Solution: The correct answers with necessary explanations are given below:(1) (a) Not True. In parallel pipes, the flow rate is proportional to its diameter and inversely proportional to its length and friction factor. In any fluid flow system, the flow rate is proportional to the square of the diameter of the pipe and the velocity of flow of fluid in the same pipe. Other options are true because: (b) Continuity equation must be satisfied in any piping network. (c) Kinetic Energy correction factor is used to compensate for the velocity fluctuation from the surface of the pipe to the center. (d) Nodal continuity must be satisfied for any piping network. (2) The Energy Grade Line is always a distance V2/2g above the Hydraulic Grade Line. EGL is parallel to HGL in uniform cross-section pipe but for varying cross-section, the EGL slopes downwards. However, the distance between the EGL and HGL will always be equal to the velocity head.
