Consider steady flow of water in the series pipe system shown below, with specified discharge. The diameters of Pipes A and B are 2 m and 1 m , respectively. The lengths of pipes A and B are 100 m and 200 m , respectively. Assume the Darcy-Weisbach friction coefficient, $f$ as 0.01 for both the pipes.
The ratio of head loss in Pipe-B to the head loss in Pipe-A is ___________ (round off to the nearest integer).
Two reservoirs are connected by two parallel pipes of equal length and of diameters 20 cm and 10 cm, as shown in the figure (not drawn to scale). When the difference in the water levels of the reservoirs is 5 m, the ratio of discharge in the larger diameter pipe to the discharge in the smaller diameter pipe is ___________. (round off to two decimal places)
Consider only loss due to friction and neglect all other losses. Assume the friction factor to be the same for both the pipes)
