Why does the size of the needle of a syringe control flow rate...
Why does the size of the needle of a syringe control flow rate better than the thumb pressure exerted by a doctor while administering an injection?
Options
- ABecause thumb pressure directly affects pressure and velocity equally.
- BBecause the pressure exerted by the doctor depends solely on thumb strength.
- CBecause the size of the needle affects the velocity squared, giving it a more significant influence on flow rate.
- DBecause the thumb pressure exerted by a doctor can be precisely measured and controlled.
Correct answer
C. Because the size of the needle affects the velocity squared, giving it a more significant influence on flow rate.
Step-by-step solution
Correct Option is : (C)
Because the size of the needle affects the velocity squared, giving it a more significant influence on flow rate.
Because the size of the needle affects the velocity squared, giving it a more significant influence on flow rate.
