Final answer:
To convert a flow rate of 210 ml/s to litres per hour, divide by 1000 to convert ml to litres, getting 0.21 L/s, and then multiply by 3600 to change seconds to hours, resulting in a flow rate of 756 L/h.
Step-by-step explanation:
To convert the flow rate of water from millilitres per second to litres per hour, we must first understand the relationship between the units of volume and time. Remember that 1 litre is equivalent to 1000 millilitres. Thus, to convert from millilitres to litres, you simply divide by 1000.
The flow rate given is 210 ml/s. To find the flow rate in litres per second (L/s), you do the following calculation:
- Divide the flow rate in millilitres by 1000 to convert it to litres: 210 ml/s ÷ 1000 = 0.21 L/s.
Next, we’ll convert seconds to hours. There are 3600 seconds in one hour. Therefore, to convert the flow rate from litres per second to litres per hour (L/h), you multiply by 3600.
- Multiply the flow rate in L/s by 3600 to get L/h: 0.21 L/s * 3600 s/h = 756 L/h.
Therefore, the flow rate in litres per hour is 756 L/h.
