Prob. 3: Consider the model house (building height is less than one ft.) shown in the figure below. The drainpipe in the figure is only 2 mm in diameter in the model as per geometric scaling. Making suitable assumptions: (a) What is the rate of flow draining when the gutter is flowing full? (b) The gutter is designed for a sudden rainstorm of up to 5 mm per hour. For this condition, what is the maximum roof area that can be drained successfully? (c) What is Red? (d) The drain installer makes a mistake and installs the drainpipe at an angle of 15o with the gutter. What is the flow rate for this configuration?
