Question

A rectangular pipe 5m long with a cross-sectional width of 0.3m and crosssectional height of 0.15m is full of running water, moving at 15m/s. This pipe then splits into 5 smaller pipes, each with a circular cross section, all with a radius of 0.12m.

1) Calculate the flow rate in the rectangular pipe.

2) Calculate the water’s speed in each of the 5 circular pipes.

3) Assuming that the circular pipes are each 2m long, and empty into the open air, how much higher is the pressure where the rectangular pipe splits into the circular ones than normal atmospheric pressure?
