The mass flow rate in a water flow system determined by collecting the discharge over a timed interval is 0 2 kg s. The scales used can be read to the nearest 0 05 kg and the stopwatch is accurate to 0.2 s. Estimate the precision with which the flow rate can be calculated for time intervals of (a) 10 s and (b) 1 min.
