For the hydraulic structure shown below: (A) What is the pressure head at points A, B? (B) What is the flow rate below the structure in cubic feet per day if the structure is 500 feet wide?

A sharp-edged orifice having a diameter of 0.0285 m is installed in a 0.25-m pipe through which a liquid having a density of 1050 kg/m3 and a viscosity of 1.5 cp is flowing. The measured pressure difference across the orifice is 120 kN/m2. Calculate the volumetric flow rate in li/s. Assume that Co = 0.61.

2. You're designing a stilling basin and you need to know the minimum length of that basin and also how much energy loss will be achieved before flow is released into the downstream channel. Given the basin width is 10-feet, the flow rate is 240 CFS, the upstream froude number is found from hydraulic modeling to be 4.0. Solve the following: • Minimum length of the stilling basin. • Energy loss within the stilling basin (Calculate both energy loss in feet and in tons). • The depth of water being released outside of the stilling basin. • The Froude Number being released from the Stilling Basin. • Look at USBR Design of Small Dams and Write a paragraph (4-5 sentences) of the recommended stilling basin you would propose for the hydraulic scenario.
