Pump

The yard pump is dripping water. Every drop is 1 ml. How many drops will be necessary before filling a bucket with a volume of 10 l? Calculate how long it will take to fill the bucket when drops fall each second.

Correct answer:

n =  10000
h =  2.78 h

Step-by-step explanation:

$$\begin{gathered} V_1=10\text{l} \\ {V}_2=1\text{ml}\to \text{l}=1:1000\text{l}=0.001\text{l} \\ n=V_1/V_2=10/0.001=10000 \end{gathered}$$

$$\begin{gathered} t_1=n=10000\text{s} \\ h=t_1\to \text{h}=t_1:3600\text{h}=10000:3600\text{h}=2.78\text{h}=2.78\text{h} \end{gathered}$$
