The mass flow rate in a water flow system determined by collecting the discharge over a timed interval is \(0.2 \mathrm{~kg} / \mathrm{s}\). The scales used can be read to the nearest \(0.05 \mathrm{~kg}\) and the stopwatch is accurate to \(0.2 \mathrm{~s}\). Estimate the precision with which the flow rate can be calculated for time intervals of

(a) \(10 \mathrm{~s}\) 

(b) \(1 \mathrm{~min}\).
