Final answer:
Uche's pumping rate in mL/s is determined by dividing the volume pumped (in mL) by the time taken (in seconds). Without specific values, we can't give an exact rate, but the flow rate can be converted to other units using appropriate conversion factors.
Step-by-step explanation:
To determine Uche's pumping rate in mL/s (milliliters per second), we first need to understand that the flow rate (Q) is defined as the volume (V) that flows past a certain point per unit time (t), given the formula Q = V/t. Since the student question does not provide a specific volume or time, let's consider a hypothetical example. If Uche's pump transferred 500 mL of water in 10 seconds, then the average flow rate would be 50 mL/s.
To convert the flow rate to other units, proper conversion factors are used. For example, if we convert to m³/s, we know that 1 L = 1000 mL and 1 m³ = 1000 L, so we'd use the following conversion: (500 mL / 10 s) * (1 L / 1000 mL) * (1 m³ / 1000 L) to get the flow rate in m³/s.
