Final answer:
The flow rate of the sampling pump calibrated on a 1 liter soap bubble flow meter in 45 seconds is approximately 1.33 liters per minute.
Step-by-step explanation:
The flow rate of a sampling pump can be determined by the volume of soap bubble that is calibrated in a given time. In this case, the pump is calibrated on a 1 liter soap bubble flow meter in 45 seconds. To find the flow rate in liters per minute, we can divide the volume of the soap bubble (1 liter) by the time it takes to form (45 seconds) and convert the result to minutes. So, the flow rate would be:
Flow Rate = Volume / Time = 1 liter / 45 seconds = 0.0222 liters/second
To convert this to liters per minute, we multiply the flow rate by 60:
Flow Rate = 0.0222 liters/second * 60 seconds/minute = 1.33 liters/minute
