Explanation:
Volume of intravenous solution to be delivered = 50 mL
1) Rate of drops per milliliter of the solution = r = 60 drops/mL
Number of drops delivered :
[tex]60 drops/mL\times 50 mL = 3000 drops[/tex]
Time required to deliver 3000 drops = t
Rate of drop solution with respect to time = R = 1 drop/second
[tex]\frac{3000 drop}{t}=1 drop/s[/tex]
t = 3000 seconds = 50 minutes (1 min = 60 seconds)
Number of drops delivered 3000.
50 minutes are required to deliver 50 mL of intravenous solutions.
2) Rate of drops per milliliter of the solution = r = 15 drops/mL
Number of drops delivered :
[tex]15 drops/mL\times 50 mL = 750 drops[/tex]
Time required to deliver 750 drops = t
Rate of drop solution with respect to time = R = 1 drop/second
[tex]\frac{750 drop}{t}=1 drop/s[/tex]
t = 750 seconds = 12.5 minutes (1 min = 60 seconds)
Number of drops delivered 750 .
12.5 minutes are required to deliver 50 mL of intravenous solutions.
