1-35. 1-36. 1-37. 1-38. 1-39. Water flows through a pipe of 5 square-inch  cross  section  at  the velocity of 3 feet per second (fps). At what velocity does it flow  through  a  constriction  in the pipe with a cross section of 3 square inches? 1. 1.8 fps 2. 3.0 fps 3. 3.6 fps 4. 5.0 fps Two  pistons  with  different  cross- sectional  areas  will  travel  at the same speed as long as the rate of fluid flow into their cylinders  is  identical. 1. True 2. False In  streamline  flow,  each  particle of fluid moves in what manner? 1. In  uniform  helical  swirls 2. In parallel layers 3. At  a  velocity  proportional  to the  cross-sectional  area  of the pipe 4. At the same velocity in the center of the pipe as along the walls Losses  due  to  friction  increase with velocity at a higher rate in turbulent  flow  than  in  streamline flow. 1. True 2. False What is inertia of fluids in a power  system? 1. The  resistance  of  the  fluid to movement or change of rate of  movement 2. The  force  required  to maintain the fluid at constant  velocity 3. The capacity to move and change  rate  of  flow 4. The  force  required  to overcome  friction 1-40. Neglecting  friction,  how  much force is required to accelerate 3 pounds of fluid from rest to a velocity  of  322  feet  per  second in 2 seconds? 1. 1.5 pounds 2. 3.0 pounds 3. 15 pounds 4. 30 pounds ANSWER  QUESTIONS  1-41  THROUGH  1-45  AS TRUE OR FALSE BASED ON THE RELATIONSHIP OF FORCE, PRESSURE, AND HEAD. 1-41. 1-42. 1-43. 1-44. 1-45. 1-46. Head is a statement of force per unit area. 1. True 2. False Velocity  head energy  caused 1. True 2. False is the loss of by  inertia. Gravity  head  depends  on  which portions of the system are exposed to open air. 1. True 2. False Friction  head  cannot  exist without  velocity  head. 1. True 2. False There can be no static head if the fluid is in motion. 1. True 2. False Which  factors  affecting  fluid action  are  classified  as  static factors? 1. Applied  forces,  inertia,  and friction 2. Atmospheric  pressure,  applied forces ,    and  inertia 3. Gravity,  applied  forces,  and friction 4. Gravity,   atmospheric pressure,   and  applied  forces 5
