(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I'll just post the question given:

You are at the clinic getting your flu shot. The syringe that is being used to deliver the

vaccine has a volume of 2.0 mL, an inner diameter of 6.0 mm, and the needle has an inner

diameter of 0.25 mm. The plunger on which the nurse has placed her finger has a diameter

of 1.2 cm.

(a) What is the minimum force that the nurse needs to apply for serum to enter you?

Take into consideration that you are a little stressed by the whole needle business so

your blood pressure is a bit high: 140-over-100 (be sure you know exactly what those

numbers mean before trying to use them in a calculation!)

(b) The nurse empties the needle in 2 seconds. What is the flow speed of the serum through

the needle?

I'm not sure exactly how to get this problem. I know you have to look into the conservation, but what variables would represent what, and what equations could be used to relate all the terms?

I'm really stuck here, any help is appreciated!
