Water from a nozzle tapers from a diameter of 12 mm to 6 mm after falling 600 mm. Determine the mass flow in kg/s.

In order to determine the flow in a rectangular channel, a 75-mm-high bump is added on its bottom surface. If the measured depth of flow at the bump is 1.25 m, determine the volumetric discharge. The flow is uniform, and the channel has a width of 1.5 m.
