Question

The Huka Falls on the Waikato River is one of New
Zealand’s most visited natural tourist attractions (see Figure
12.29). On average the river has a flow rate of about 300,000
L/s. At the gorge, the river narrows to 20 m wide and
averages 20 m deep. (a) What is the average speed of the
river in the gorge? (b) What is the average speed of the water
in the river downstream of the falls when it widens to 60 m
and its depth increases to an average of 40 m?

A sump pump (used to drain water from be basement of houses built below the water table) is draining a flooded basement at rate of 0.750 L/S, with an output pressure of 3.00105N/m2 . (a) The water enters a hose with a 3.00-cm inside diameter and rises 2.50 m above the pump. What is its pressure at this point? (b) The hose goes over the foundation wall, losing 0.500 m in height and widens to 4.00 cm in diameter. What is the pressure now? You may neglect frictional losses both parts of the problem.
