Predict Question:
Predict Question: If you increase the flow tube radius, what will happen to the pump rate to maintain constant pressure?
Your answer : b. The pump rate will decrease.
Stop & Think Questions:
When the piston of the pump reaches its lowest point, the volume remaining in the pump is the
If you increase the right flow tube radius, what will happen to resistance and flow rate?
If the left flow tube represents the pulmonary veins, what does the left source beaker represent?
