The video demonstrates step-by-step procedures for measuring flow rate using practical lab tools for:

  • Liquid flow rate (water) using a pump + rotameter and a collection/measurement setup
  • Gas flow rate using a U-tube manometer-like setup (“U pipe”) + compressor, with timed collection and volume measurement

Methodology / work steps (detailed)

A) Measuring liquid flow rate (water) using pump + rotameter

  1. Prepare the pump

    • Turn on the pump by:
      • Connecting the pump cable to a socket
      • Pressing the ON button
    • This fills the water tank.

  2. Set the rotameter float level

    • After the system reaches an overflow/steady state, adjust the tap opening
    • Goal: raise/lower the rotameter float to a desired height

  3. Hold conditions constant

    • Once the float height is constant, keep the setting unchanged.

  4. Collect the output for a fixed time

    • Collect the water using a beaker for a certain time interval.

  5. Measure collected volume

    • Measure the collected water volume using a measuring cup
    • Record the volume

  6. Repeat for different float heights

    • Repeat the same steps while varying the rotameter float height

B) Measuring gas flow rate using U-pipe (U-tube) + compressor

  1. Prepare the compressor

    • Turn on the compressor.

  2. Set the inlet/tap opening to achieve a height difference

    • Adjust the tap opening so air enters
    • Goal: the liquid level difference in the U-tube reaches the desired height difference

  3. Hold the height difference constant

    • Wait until the height difference remains constant.

  4. Collect the discharged fluid/output

    • Collect the resulting output using a beaker glass for a certain time interval.

  5. Measure volume

    • Measure the collected volume using a measuring cup
    • Record the volume

  6. Repeat for different height differences

    • Repeat with variations in the liquid height in the U-tube
