Class 1 C.Class1 2. If the desired volume nlow rate need to be decided what is the class for this series pipeline syste B. Class 3. If the sizes of pipes, the types of the minor losses hyminor, and the volume flow rate Q and the total head B. Class II C.Class1 ha on a pump are known for the series pipeline system, and the pressure drop needs to be determined, what is the elass for this problem? C. Class i 8Class C 4. For a parallel pipeline system with 2 branches, if the energy loss in one branch is 2.0 m, what is total energy loss at the main head pipe? B. 4.0m C. 1.0m D. cannot be decided A. 2.0m For a parallel pipeline system with 2 branches, if the volume flow rate in both branches is 2.0 m2 /s, wha is volume flow rate at the main head pipe? 5. B. 2.0 m*/s B. 4.0 m3/s C. 1.0 m2/s D. cannot be decided For a series pipeline system, if the pipe size in the discharge line is increased, then which are the statements below?(multiple choices) 6. A. Volume flow rate in the system is increased B. Velocity in the discharge line is decreased C. Velocity in the discharge line is increased D. Energy loss is decreased E. Energy loss is increasedExplanation / Answer
1) Class III (The general layout of the system is known along with the desired volume flow rate. The size of the pipe required to carry a given volume flow rate of a given fluid is to be determined.)
2) Class II (The system is completely described in terms of its elevations, pipe sizes, valves and fittings, and allowable pressure drop at key points in the system. You desire to know the volume flow rate of the fluid that could be delivered by a given system)
3) Class I (The system is completely defined in terms of the size of pipes, the types of minor losses that are present, and the volume flow rate of fluid in the system. The typical objective is to compute the pressure at some point of interest, to compute the total head on a pump, or to compute the elevation of a source of fluid to produce a desired flow rate or pressure at selected points in the system)
4) Option A- 2.0m (In parallel pipeline Energy loss is constant)
5) Option B- 4.0 m3/s ( In parallel pipeline discharge is added)
6) Options B,E
velocity will decrease and energy loss will increase
