Weigh the cylinder and liquid, and then calculate the density of the liquid. Repeat this procedure to find the density of each liquid. 2) Determine the density of each of the above, using a hydrometer and an ungraduated cylinder. Read the density from where the liquid crosses the hydrometer's scale. 3) Weigh and record the mass of an unknown metal cylinder. Also record the identity of the unknown metal cylinder (A, B, C, or D).

1. I:E Ratio is the amount of time for inspiration compared to the amount of time for exhalation 2. Expiratory time should normally be greater than inspiratory time (1:2, 1:3) 3. COPD pts need more time to exhale (I:E ratio- 1:4, 1:5) 4. Increasing the flow rate will increase the time of exhalation.
