Answer Key: Self-Test C-1.15

  1. Generally speaking, what two types of flow are possible in a piping system?
    1. laminar
    2. turbulent
  2. What term is used to describe a liquid’s internal resistance to flow?
    1. viscosity
  3. When fluid velocity is low, laminar flow usually results.
  4. When fluid velocity is high, turbulent flow usually results.
  5. Another name for laminar flow is streamline flow.
  6. List the six factors that govern the pressure drop due to friction in a piping system.
    1. viscosity of liquid
    2. length of pipe
    3. velocity of flow
    4. size and type of pipe
    5. number and type of fittings and valves
    6. number and degree of bends
  7. When fluid velocity is low, high static pressure results.
  8. When fluid velocity is high, low static pressure results.
