Why does oil miscible in solution of surf and water?
Presumably you mean surfactant and water? A classic surfactant molecule has a polar, hydrophilic end and a non-polar hydrocarbon liophilic end. With enough of a suitable surfactant, oil droplets will form with the liophilic part of surfactant molecules dissolved in the droplets and water molecules attached to the hydrophilic part of the surfactant. The oil disperses in the water.
When do fetuses begin to produce surfactant?
Fetuses begin to produce surfactant between weeks 24 and 28.
Is a surfactant a heterogeneous mixture?
dff
Is a surfactant an emulsifying agent?
Yes
What is the head of a surfactant molecule?
Hydrophilic
Does surfactant affect airflow?
Surfactant improves airflow in several ways. First, it maintains airway stability by preventing airway film collapse of the airway walls. Second, surfactant modulates airway wall thickness and diameter by regulating liquid balance. In other words, the dysfunction of surfactant airways might be one of the mechanisms leading to increased airway resistance [seen in in obstructive lung diseases].Source:J Hohlfeld, H Fabel, and H Hamm.

What effect does a deficiency of surfactant exert on lung compliance?
Increased compliance result

As a result of the tidal volume change what happens to the flow into each lung and total air flow?
Airflow increases when surfactant is applied because the resistance to lung inflation has been reduced.
What changes the direction of airflow and is caused by earths rotation?
The coriolis effect
Will round computer cables improve the airflow around the chassis of the pc?
The shape of tyhe computer cable will have very little effect onthe airflow.
What do surfactant do?
A surface-active agent 'surfactant' usually cleans something. ie -soap is a surfactant.
Effect of filter media density on it performance?
The denser the media the less airflow through it.
What is ground effect and how does it work?
The result of the interference of the surface of the Earth with the airflow patterns about an airplane.
Surfactant that cover the respiratory membranes?
Surfactant is pleural fluid.

What do Type 2 alveolar cells secrete?
secrete surfactant
